Question

In general is it harder to change the temperature of metal (like

a car hood) or of water? Which requires more heat energy to change
the temperature of metal or of water?

Answer 1

Since it requires more heat energy change the temperature of water and since specific heat is a measure of how much energy is needed to change the temperature of a substance, water must have a higher specific heat.

it takes more energy to warm the same amount of water as it does metal to the same temperature.
