The metal heats faster than the water because it requires less energy to heat it up (it has a lower heat capacity). 4. Why do you think different substances heat up and cool down at different rates? ... Water has a very high potential energy due the intermolecular forces between the polar water molecules.
because it helps to move something from one side to another
Kinetic energy = 1/2 * mass * velocity^2 so Ke = 1/2*(155*10^3 g)*18^2 which is 25,110,000 joules.
