a) They collide and stick to one another
b) Inside of the star called Sun. On the earth we don't have such materials that would withstand very high temperatures.
c) As it commonly happens today: boil water, get high-temperature steam, rotate turbine connected to a generator and get electricity
d) Sorry, I don't see any charts.
Answer: Friction between the two surfaces converts kinetic energy into thermal energy.
Explanation: Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
