The amount of energy required to elevate the temperature of one gram of a substance one degree Celsius
This gives the amount of heat per m² of active solar surface that the collector, including its heat medium, can store at a temperature increase of 1 Kelvin.
The specific heat capacity of a material is the amount of heat required to raise the temperature of 1 kg of the material by 1 °C. Hot and Cold
The quantity of heat required to raise the temperature of one gram of a material by 1 oC or 1 oK.
The amount of heat needed to increase the temperature of 1 kg of a substance by 1 K.
Amount of energy required to raise the temperature of 1 g of a substance 1C. The value for liquid water is 1.
the amount of energy required to raise the temperature of one gram of a substance by one Celsius degree.
The quantity of heat required to change the temperature of one unit weight of a material by one degree.
the amount of heat required to raise the temperature of a unit mass of a substance by one degree.
the quantity of heat (energy) needed to raise the temperature of unit of mass of a substance by a unit of temperature change.
(Or specific heat.) The heat capacity of a system divided by its mass. It is a property solely of the substance of which the system is composed. As with heat capacities, specific heats are commonly defined for processes occurring at either constant volume () or constant pressure (). For an ideal gas, both are constant with temperature and related by = + with the gas constant. For dry air at 273 K, For moist air, the specific heat capacities of the dry air and water vapor must be combined in proportion to their respective mass fractions. Dutton, J.

Specific heat capacity, also known simply as specific heat (Symbol: C or c) is the measure of the heat energy required to raise the temperature of a given amount of a substance by one degree. Commonly, the amount is specified by mass; for example, water has a mass-specific heat capacity of about 4184 joules per kelvin per kilogram. Volume-specific and molar-specific heat capacities are also used.
