Molar Specific Heat
The molar specific heat of a matter is an amount of heat required to raise the temperature of one mole of substance by 1 °C or 1 °K.
Molar Specific Heat Capacity is denoted by the third alphabet of the English language “c”(lower case) and its unit is J/(mol K) or J/(mol °C). Mathematically Molar Specific Heat is given by the following formula:
c = Q/(n ΔT)
Q = ncΔT
where,
- Q is the amount of energy required to chagne temperature by ΔT
- n is the number of moles of the substance
- c is the specific heat of the system under considertation
Note: This formula tells us how much energy is required to raise the temperature of n moles of solid by ΔT.
Specific Heat Capacity
Specific Heat Capacity is one of the fundamental physical properties of matter that describes the amount of heat energy required to increase the temperature of 1 kg of matter by 1o Celsius. the SI unit of Specific Head Capacity is J/(KgK), but other than this Specific Heat Capacity is also measured in cal/(gK) or J/(g°C). For any matter, specific heat capacity depends on its composition, density, and the physical state of the matter, as for the different states of water specific heat is different.
With this article, we will learn about the concept of Specific Heat Capacity and the other concepts in thermodynamics related to it.
