Heat capacity is the amount of heat energy required to raise the temperature of a substance by one degree Celsius.
Heat capacity is measured using a calorimeter, which is a device that can accurately measure the heat exchange between a substance and its surroundings.
Heat capacity is important because it helps us understand how much energy is needed to change the temperature of a substance. It also plays a role in various industrial processes and can be used to determine the efficiency of a system.
The heat capacity of a substance is affected by its mass, temperature, and chemical composition. It can also vary with changes in pressure and the phase of the substance (solid, liquid, gas).
Specific heat is the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius. Heat capacity is the total amount of heat energy required to raise the temperature of an entire sample of a substance. The two are related by the mass of the substance, with specific heat being the heat capacity per unit mass.
