The amount of heat energy contained in a body depends on its :

1. mass
2. temperature
3. material of the body
4. all of the above

all of the above

Reason — The amount of heat energy contained in a body depends on its

1. Mass — The greater the mass of a body, the more heat energy it can contain, assuming all other factors remain constant.
2. Temperature — The temperature of a body directly influences the amount of heat energy it contains. Higher temperatures indicate higher amounts of thermal energy.
3. Material of the Body — Different materials have different specific heat capacities, which determine how much heat energy is required to raise the temperature of the material by a certain amount.
