WebLatent heat and enthalpy In this section we will develop the relationship between latent heat and enthalpy. Latent Heat As we have noted, you can transfer energy by heating without increasing temperature. This happens during phase changes. In a phase change, the heat capacity becomes inﬁnite. The appropriate term to consider is now latent heat. WebHeat capacity is defined as the amount of heat energy required to raise the temperature of a given quantity of matter by one degree Celsius. Heat capacity for a given matter depends on its size or quantity and hence it is an extensive property. The unit of heat capacity is joule per Kelvin or joule per degree Celsius. Mathematically,
