Heat energy is measured in units called joules or calories. 1 calorie is the amount of heat energy needed to raise the temperature of 1.0 g (mL) of water.

Specific Heat Quantity of energy needed to increase the temperature of one gram of a substance by one degree Celsius/Kelvin Every substance has its own.

 Different substances require different amounts of heat to change their temperature.  Objects that require more energy have a high heat capacity like.

 Heat is defined as the transfer of energy across the boundary of a system due to a temperature difference between the system and its surroundings.
