In thermodynamics, the specific heat capacity (symbol c) of a substance is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. It is also referred to as massic heat capacity or as the specific heat.
11 Αυγ 2024 · Learn what specific heat and heat capacity are, how they are calculated, and what units they use. Find out the specific heat values of common substances and the significance of water's high specific heat.
Specific Heat Capacity. The specific heat capacity is the amount of heat it takes to change the temperature of one gram of substance by 1°C. So, we can now compare the specific heat capacity of a substance on a per gram bases. This value also depends on the nature of the chemical bonds in the substance, and its phase.
The table of specific heat capacities gives the volumetric heat capacity as well as the specific heat capacity of some substances and engineering materials, and (when applicable) the molar heat capacity.
29 Αυγ 2022 · Heat capacity is the amount of heat required to raise the temperature of an object by \(1^\text{o} \text{C}\). The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of the substance by \(1^\text{o} \text{C}\).
Unlike the total heat capacity, the specific heat capacity is independent of mass or volume. It describes how much heat must be added to a unit of mass of a given substance to raise its temperature by one degree Celsius. The units of specific heat capacity are J/(kg °C) or equivalently J/(kg K).
14 Αυγ 2024 · Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. The specific heat capacity of a material is a physical property as well as an extensive property since its value is proportional to the size of the system being examined.
