  • Heat Capacity
    The amount of heat needed to change the temperature of a substance, proportional to temperature change.
  • Specific Heat Capacity
    Heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius or Kelvin.
  • Molar Heat Capacity
    Heat required to raise the temperature of 1 mole of a substance by 1 degree Celsius or Kelvin.
  • Temperature Change
    The difference in temperature resulting from the application of heat to a substance.
