Question

What do you mean by molar specific heat at constant pressure, \[Cp\]and molar specific heat at constant volume, \[Cv\] ​?

Answer 1

Hint: The question belongs to thermodynamics and can be explained by the flow of heat in the different masses taken at specific conditions.

Complete Step by Step Solution:
Heat is one of the forms of energy which is required to raise the temperature of the particles in nature. Here, Heat capacity is defined as the amount of energy required to raise the temperature of a certain mass by 1 kelvin or 1 degree Celsius. In this theory thermodynamics is the best way to explain it, as thermodynamics is defined as per its name ‘the flow of heat’ or ‘the motion of heat’ in the particle and surrounding.
Specific heat capacity can be defined as the amount of heat energy required to raise the temperature of the 1 gram mass given by 1 kelvin or 1 degree Celsius.
Molar specific heat at constant pressure, \[Cp\] can be defined as the amount of energy in the form of heat required to raise the temperature of 1 mole of the particles present in any phase by 1 kelvin or 1 degree Celsius.
Molar specific heat at constant volume, \[Cv\] can be defined as the amount of heat required in the form of heat energy to raise the temperature of 1mole of the particles present in any phase by 1 kelvin or 1 degree Celsius.

Additional Information: 1 Molar of substance can be defined as the presence of 1 mole of solute in 1 litre of solution. ‘Molar’ is the unit of the molarity.

Note: Number of moles can be defined as the ratio of the mass and molar mass (mass of one mole) of a certain atom. 1 mole of substance contains Avogadro's number of particles (atoms or molecules).
