Different materials will change temperature at different rates when exposed to the same amount of heat. This is because the different materials absorb heat at different rates.

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.

It should be cryosphere and hydrosphere
