How does the elasticity of a rubber band change in different temperatures? Rubber can be made with two things: synthetic rubber and natural rubber. 75% of rubber today is made of synthetic rubber, created during WWII. Natural rubber is made from the rubber tree, the rubber tree’s scientific name is Hevea Brasiliensis. They are primarily found on plantations in Southeast Asia and tropical West Africa. Natural rubber has been used for over 1000 years; it was first used by South and Central American people, who used it to make balls containers, shoes and for water proofing fabrics.
Rubber is used in everyday things such as, car tires, rubber bands, swimming caps and many other things. Russian scientist Sergei Vasiljevich Lebedev invented synthetic rubber in 1910; it came to be as a result of a natural rubber

The climate of a certain area can change physical or chemical properties of almost anything. For example if you moved ice from a cold climate to a warm climate then the ice would physically change into water. Another example is if you put cake batter into a hot oven it will turn into cake after a specific amount of time. These types of changes can happen over long periods of time or suddenly. Generally, with data from previous studies, heat tends to make things spread out or get looser; the molecules tend to spread out in warmer situations. Cold has the tendency to make the molecules in different objects come closer together and become tight and not very flexible. For example the molecules in water when its warm are much further apart in its liquid state of matter compared to how close the molecules are when its cold are much closer together. Thermodynamics is the branch of physical science that deals with the relations between heat and other forms of energy and relationships between all forms of energy. There are four laws of Thermodynamics that talk about the relations with heat and other forms of
Climate change is a change in the average global or regional weather patterns. Climate changes includes factors such as; temperature, precipitation, humidity, wind and seasons, influenced by oceans, land surfaces and ice sheets. This plays a
Weather is the day-to-day state of the atmosphere in a region. Overall, weather describes short-term conditions that are subject to quick, and sometimes unexpected change. Climate is defined as the weather conditions prevailing in an area over a long period. Unlike weather, climate is not subject to sporadic change. Most meteorologists define climates by looking at the average temperatures and precipitation levels over a long period of time. This brief essay outlines how weather and climate differentiate, while also showing how they relate to and differ from
During this laboratory, the properties of silicon rubber and its selectivity were studied using different agitation and flow rates of CO2. Because of these properties, it is a well known and used material in the industry to imitate different processes and biochemical reactions that occur in the human body. Moreover, it is an ideal material for these applications as it allows diffusivity of CO2 concentration depending on the flow rate or driving force.
The climate alternates when the heat is added or released from the earth. And as the climate changes, it also affects the planet drastically including its essential elements, for example water, air and soil. How Is Climate Change Affecting Water? The increase in heat evaporates the water more causing less supply and more demand on water.
When climate change occurs; there is increase in temperature. When temperature rises, unusual changes occur on Earth. For example, it can result into more floods, droughts, or intense rain, as well as severe heat waves. Oceans and glaciers have also experienced some changes. According to NASA: Sea levels have risen 3 inches and extreme weather in the U.S. has increased by 30 percent. In Greenland and Antarctica, ice sheets have lost 4.9 trillion tons of ice.
If someone could peek inside my mind, they’d see an amazing ninja scene playing out at all times. Me, turning all wrong things right—in some sort of hero outfit. It’s one giant movie. And that’s the beauty of movies! I’m convinced that the reason people (myself included) are so attracted to movies is that there is, more often than not, clearly resolved conflict that satisfies our desire to see justice. The bad guy got caught! Justice. The jock lost the girl! Justice. The mystery was solved! Justice. I wish that all conflicts were so easy to tie up!
Climate change has been created by many different factors. Including methane emissions from animals, like livestock. Methane being released into the atmosphere causes a change in the earth’s climate. A change in the earth’s solar activity has also contributed to global temperature change. These changes are called sunspots and they change the earth’s solar radiation levels. This causes short term warming cycles on the planet. Permafrost is frozen ground that is mainly in the northern hemisphere. It releases carbon and methane into the atmosphere when it melts. This accelerates global warming by adding to the concentration of carbon in the atmosphere. Water vapor holds in heat in the atmosphere due to the greenhouse effect. As temperatures rise all of these factors also increase in turn.
Nobel Prize winner Ernest Hemingway is known throughout the world for his writing but Key Westers know him as one of their own. His life and works are still celebrated in Key West, Florida, his residence for nearly a decade ("Hemingway-The Legend”). Hemingway lived there with his wife, Pauline ("Hemingway-The Legend”). Key West residents commemorate the author, whose home is now a museum, during the Hemingway Days festival with events like the “Papa” Hemingway lookalike contest.
Charles Goodyear was a man of determination, He dedicated most of this life to creating vulcanized rubber it is more or less a moldable and water-resistant rubber. He received is patent in 1844 for his invention.
Second amendment rights are a controversial subject, but in her article, “A Peaceful Woman Explains Why She Carries a Gun,” Linda M. Hasselstrom explains why those rights are important to her. Hasselstrom uses logos, pathos, and ethos to entertain readers and to inform them of why she carries a gun.
According to the IPCC (2007), climate change refers to a change in the state of the climate that can be identified (e.g. using statistical tests) by changes in the mean and the variability of its properties, and that persists for an extended period, typically decades or longer. It refers to any change in climate over time, whether due to natural variability or as a result of human activity. Studies suggest that the global climate has been warming and will probably continue to do so. Thus complicated process drives an array of effects, from distinct events like extreme weather to long-term impacts that vary by location, intensity,
Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).
Presently elastic is found In blends, that are utilized in development comes and improvements of roadways. Elastic is by and large reused from late disposed of tires, which might even be reused. The tires are made into new stock, regardless of whether it 's inside of The kind of bigger rolls or adaptable elastic segments. As an asset, reused elastic might be a glorious there are more than 250 million tires that are tossed yearly (Rubber band versatility). Actually, a few people have made whole homes out of reused elastic the essential gum flexible that was suitable for tires was made of gum versatile that was proper to be made into tires, was made of a blend of vinylbenzene and hydrocarbon, manufactured measured at I.G. Farben. The Union of Soviet Socialist Republics, alluded to as its vinylbenzene hydrocarbon elastic. the most kind of elastic made these days is presently counterfeit. Truth be told, {southeast asia|Southeast Asia|geographical ara|geographic area|geographical region|geographic region} nations are at present the more-predominant makers of normal elastic as an aftereffect of the ascent measures of gum flexible. There are numerous different sorts of gum flexible, each marginally totally distinctive qualities like silicone, neoprene, nitrile, and EPDM elastic. Elastic is framed by warming a blend of elastic, sulfur, and distinctive chemicals into strips, that are expelled into tubes and cured into groups. Elastic groups are made of common elastic/latex or gum
For example, plants are delicate and to grow an abundance of it, it is best to put them in a comfortable temperature range Each range varies due to the differences of plants. With the increasing temperature, it plays a role in where, how and when plants may grow. Northern states will be able to produce crops now that the temperature went up but tropical areas will have harder time producing crop because it will be too hot for plants to grow(Climate).. Increase in heat will also change the productivity of fisherman trying to catch fish (Global). Salmon for example have a hard time thriving in warm water, so that’s a Marine ecosystem we are affecting
There are reasons why natural rubber was chosen to make part of tyres. The first reason is natural rubber has high tensile strength. Because of this high tensile strength natural rubber can hold shape and is more flexible. Second, natural rubber is more environmental friendly compared to synthetic rubber. This is because it is originally derived from latex which produced from tree. Besides, natural rubber is a biodegradable material. It can be degrade rapidly especially under some extreme conditions such as soil. Soil contain some microorganism, bacteria or fungi it help to degrade rubber.
