You are on in line skates at the top of a small hill. Your potential energy is equal to 1,000. J. The last time you checked, your mass was 60.0kg.?

At the top of the hill, the ball has 100 J of potential energy. Explain what happens to Mechanical Energy, Kinetic Energy and Potential Energy as the ball rolls down and reaches the bottom.

The constant pressure molar heat capacity, C_{p, m}C p, m , of nitrogen gas, N_2N 2 , is 29.125/text{ J K}^{-1}/text{ mol}^{-1}29.125 J K - 1 mol - 1 at 298/text{ K}298 K.
