heat capacityIn physics, the quantity of heat required to raise the temperature of an object by one degree. The specific heat capacity of a substance is the heat capacity per unit of mass, measured in joules per kilogram per kelvin (J kg−1 K−1). How to thank TFD for its existence?

| Different outdoor electric patio heaters come with different heat capacities. Table 1 gives the internal heat gains due to occupants and equipment, solar transmission, and the total heat conductance due to heat transfer across the building fabric and infiltration (note that the conductances are approximate, as the sensible and latent heat capacities of the zone air are temperature dependent; the zone temperature is a variable in this example). This change in heat capacity at the glass transition can be calculated as the difference between the heat capacities before and after the transition region. |
