Measuring Thermal Energy

VIEWS: 4 PAGES: 6

									Measuring Thermal
    Energy
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.
   Thermal Energy Equation
Variable         Ending Units
Q= Thermal Energy       J or cal
m= mass                 kg or g
▲T= temp. change        K or °C
C= Specific Heat    J/(kg. K) or
                    cal/(g .°C)
    Thermal Energy Equation

        Q= m x ▲T x C



*▲T = final temperature – initial
 temperature
