1 Measuring Thermal Energy

2 Different materials need different amounts of heat to produce similar changes in their temperatures.  Specific Heat- the amount of energy it takes to raise the temperature of a material’s mass.

3 Thermal Energy Equation Variable Ending Units Q= Thermal EnergyJ or cal m= masskg or g ▲T= temp. changeK or °C C= Specific HeatJ/(kg K) or cal/(g °C)..

4 Thermal Energy Equation Q= m x ▲T x C *▲T = final temperature – initial temperature

5 Thermal Energy Equations Q m ▲T▲TC XX....

6 1. Q m= ▲T X C Q 2.▲T= m X C 3. Q C= m X ▲T
