closes the tap and opens the jar lid easily. Explain why it open easily when placed under hot water for a few mins. Answer: When particles are cold there is barely any movement, and the pickle jar just came out of the cold fridge. I know that when heat is added to a substance, the particles move faster. So when my little sister puts the lid under hot water the particles move faster and the spaces between the particles increase which allows them to bounce off of each other making them more separated

also absorbs the heat from the surrounding air. All air conditioner systems work in the same way. It does not matter whether the air conditioner is a ductless unit or window

different uses. It can be used to heat homes, cook food, and generate electricity. Thermal energy, however, is not the same as heat. Heat is energy transferred between substances or systems due to a temperature difference between them. Therefore it is correct to say that a system contains thermal energy, but it is incorrect to say that it "contains" heat. This is because heat refers to energy that is transferred from one thing to another. The quantity of heat transferred by a substance is reliant

cooling is a method of heat removal from components and industrial equipment. As opposed to air cooling, water is used as the heat conductor. Water cooling is commonly used for cooling automobile internal combustion engines and large industrial facilities such as steam electric power plants, hydroelectric generators, petroleum refineries and chemical plants.[1] Other uses include cooling the barrels of machine guns, cooling of lubricant oil in pumps; for cooling purposes in heat exchangers; cooling

The Effect of Varying Temperatures on the Gill Movement of Carassius Auratus Overview: This lab was conducted with the purpose of confirming the trait of homeostasis among goldfish. During the experiment, it was recorded that the fish would increase gill movement when placed in colder water two out of the three trials. However, the results showed no significant difference in gill movement in various temperatures of water. This has very little effect on the broad field of science since our only

streams into the sun’s atmosphere and out into space. This energy that lights and heats the earth (14). The secret of the sun’s power lies in its center, or core. Core temperatures reach more than 27 million degrees Fahrenheit (in Celsius it reaches up to 15 million degrees). The plasma is about 150 times denser than water (Koehler 14). Under a massive amount of pressure heat and burning happens (Jefferis 10). During the heat and burning process, particles of hydrogen join together, or fuse to make hydrogen

Toronto's water supply, is now drawn from deep within it to be used for air conditioning. At the bottom of Lake Ontario, highly dense cold water can be found. During winter, the water in Lake Ontario drops to cool temperatures, and this surface water sinks to bottom of the lake when winter passes. Since this cycle continues every year, chilled water will always be found at the bottom of his lake, allowing for this water to be a completely renewable energy source. An initial study was conducted in 1981

Peltier devices. The Peltier device is just one specific example of a thermal engine. All of these engines must comply with Carnot’s law. We will check whether this is true or whether we have a perpetual mobile… Usually Peltier devices are applied as heat pumps. We will measure it 's efficiency in this mode. Since the cooling load of most typical battery compartments is not high,

Ivan S M Hewitt. Introduction to Building Environment and Construction - Environment Design Audit - PART A. BUIL1166. Luke Olsen. Energy: The Shard uses a CHP (combined heat and power) plant, which provides 1.131MW of electricity and 1.199MW of hot water at high efficiency to the surrounding area. The CHP system utilises waste heat for heating and hot water. This system reduces carbon emissions and also contributes to low carbon footprint of building. The Shards consumption will be more than 30% less

The atmosphere is an amazing creation. It contains many things that help make this world a place where we can live. The atmosphere contains ozone. That helps protect our skin from harmful sun rays. Many layers make up our atmosphere. There are five main layers, the troposphere, stratosphere, mesosphere, thermosphere, and lastly the exosphere. Each layer has a different purpose. Clouds are located in the atmosphere and are a big part of the water cycle. There are different types of clouds and they
