Heat capacity is the amount of heat energy required to raise the temperature of a substance by one degree Celsius.
Heat capacity can be measured by performing a calorimetry experiment, where the heat energy absorbed or released by a substance is measured as it undergoes a temperature change.
The heat capacity of a system can be affected by the type of substance, its mass, and its temperature. Other factors such as phase changes and chemical reactions can also impact the heat capacity.
Heat capacity and specific heat are related by the equation C = m x s, where C is the heat capacity, m is the mass of the substance, and s is the specific heat. Specific heat is the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius.
Knowing the heat capacity of a system is important in understanding how much heat energy is needed to change its temperature, as well as in designing and controlling processes that involve heat transfer.
