Unformatted sample text from the term paper:
proof, as in recent years), that every substance, whether liquid, solid or gas, has molecules. The more the molecules move around, lighter and more "flexible" it becomes. For example, a
block of ice is very solid, meaning the molecules are barely moving within it (though they are moving). When that ice becomes water, however, the molecules move around more; and
when that water becomes steam, the molecules move around even more quickly. Heat comes into the situation because whenever heat is applied to
a substance, it starts the kinetic chain going. Going back to our ice cube-water-steam example above, heat applied to ice causes the molecules to move and the ice to melt.
Keep on applying heat and the molecules move faster and become steam. In short, there is little difference between the chemical compounds of ice and steam (both consist of two
molecules of hydrogen and one of oxygen). But heat determines the kinetic energy of those forms of H2O, and therefore determines the physical composition of the molecule.
What is heat? What is temperature? What is the relationship between heat and temperature and how are they different? Heat is more than being hot.
Heat can be described as a type of energy that flows between two samples of matter due to difference in temperature (Helmenstine, 2011). To put it more simply, heat is
energy associated with molecular movement that can be transmitted through solids and fluids through conduction (and through fluids by a manner known as convection). When we physically convert our ice
cube into water by using heat, for example, were doing so through conduction, because molecules are more still and ice is a solid. But converting our water into steam is
