Heat Capacity and Specific Heat

  • very important concepts in meteorology....

  • Heat Capacity: ratio of the amount of energy absorbed to the associated temperature rise.

  • Example: if it takes 10 calories to raise the temperature of a glass of water by 2 C, then the heat capacity of the glass of water is 10 calories/2C = 5 calories per C.

  • Specific Heat: the heat capacity of a substance per unit mass

  • Example: for water, it takes 1 calorie to raise the temperature of 1 gram of water by 1C. So the specific heat for water is 1cal/gram C
