Understanding Heat Capacity and Work: Clarifying Misconceptions

In summary, heat capacity is the amount of heat energy required to raise the temperature of a substance by 1 degree Celsius, while specific heat is the amount of heat energy required to raise the temperature of 1 gram of a substance by 1 degree Celsius. Heat capacity is related to work through the first law of thermodynamics and can vary for different substances. It cannot be negative, unlike specific heat which can be negative in rare cases. Understanding heat capacity and work can have practical applications in everyday life, such as in cooking, heating and cooling systems, and industrial processes, and can also aid in making informed decisions about energy efficiency and conservation.

In defining the heat capacity of a subatance as the constant relating change in temperature to change in heat, is it assumed that the system does no work? Does it really say (heat capacity is the constant relating heat change to temperature change when the system does no work)?

There is a ##c_v## and a ##c_p##. The latter is larger -- that is an indication the system does work.
