Specific Heat vs. Heat capacity Specific heat units: or This is oC Since it is a , Celsius or Kelvin are interchangeable.
Specific Heat vs. Heat capacity Specific heat units: or Heat Capacity units:
It took 74. 9 J of heat to raise the temperature of 10 It took 74.9 J of heat to raise the temperature of 10.0 g of a substance 8.50oC. Determine the specific heat of the substance. Hint: focus on the desired units.
It took 74. 9 J of heat to raise the temperature of a 10 It took 74.9 J of heat to raise the temperature of a 10.0 g of a substance 8.50oC. Determine the specific heat of the substance. 74.9 J = 0.881 10.0 g 8.50 oC The units match!
How many calories of heat are evolved if 44.7 g of Al undergoes a cooling change of 15.0 oC? (specific heat of Al = 0.214 cal/g•K) 44.7 g 15.0 K = cal K vs. oC? ’s are the same! WHY?
