WebThe goal in defining heat capacity is to relate changes in the internal energy to measured changes in the variables that characterize the states of the system. For a system consisting of a single pure substance, the only kind of work it can do is atmospheric work, and so the first law reduces to dU = d ′ Q − P dV. (28) WebThe slope of this line is again related to the heat capacity. However, this time it is the heat capacity of the liquid. Once the temperature reaches the boiling point of 100 °C the temperature is again constant as the liquid is converted to gas.
