Specific Heat

 

1.      Specific Heat Capacity [c](or Specific Thermal Capacity)

§         The energy involved in changing the temperature of a kilogram of substance by 1°C

§         The unit is joule per kilogram per degree [J/kg°C]

 

Water

4.2kJ/kg°C

Blood

3.78 kJ/kg°C ?

 

2.      Specific Latent Heat

§         energy involved in the state change of a kilogram of substance

§         Unit J/kg

§         ice/water: 336kJ/kg; water/steam: 2270kJ/kg

 

3.      Thermal Capacity [C]

§         Energy involved in changing an object’s temperature by one degree

§         J/°C

§         If object has mass m, and is made of a substance of specific heat capacity, c, then C = mc
