Natural Rubber Band Change

Decent Essays

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 …show more content…

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
