1. Specific Heat mC  T

2. Specific Heat The amount of heat energy a material requires to raise its temperature is a characteristic that can be used to identify it. This is called heat capacity, Cp. It is measured in Joules per gram per degree Celsius The heat energy in an object can be written and calculated by the following equation:

3. “Em-cat” - m is mass in grams - Cp is specific heat of the substance  is the final temperature minus the initial Temperature

4. Calculate heat to raise temperature How much heat is required to raise the temperature of 2.5 grams of copper from 25 to 55 o C? The specific heat of copper is 0.385 J/g o C.

5. Other calculations Possible Determine specific heat knowing mass and temperature and specific heat of one substance Heat into one substance = - Heat out of the other

7. Other calculations Possible Predict final temperature knowing specific heats and masses. Heat into one substance = - Heat out of the other
