1.	Define C, and C. Derive an expression for the ratio of C,/C, for a diatomic gas
Answer» CP is the specific heat at constant pressure. It is the amount of energy released or absorbed by a unit mass of substance with the change in temperature at constant pressure. In other words, it is the energy transferred between a system and its surrounding under constant pressure.. CV is the amount of heat energy that a substance absorbs or releases (per unit mass) with the change in temperature where a volume change does not occur. In other words, it is the heat energy transferred between a system and its surrounding without any change in the volume of the system. Relationship Between CV and CP The following relationship can be given considering the ideal gas behavior of a substance. CP – CV = R Where r is the universal gas constant. The ratio between CP and CV is the specific heat ratio, γ. Γ = CP /CV

Define C, and C. Derive an expression for the ratio of C,/C, for a diatomic gas

Answer»

CP is the specific heat at constant pressure. It is the amount of energy released or absorbed by a unit mass of substance with the change in temperature at constant pressure. In other words, it is the energy transferred between a system and its surrounding under constant pressure..

CV is the amount of heat energy that a substance absorbs or releases (per unit mass) with the change in temperature where a volume change does not occur. In other words, it is the heat energy transferred between a system and its surrounding without any change in the volume of the system.

Relationship Between CV and CP

The following relationship can be given considering the ideal gas behavior of a substance.

CP – CV = R

Where r is the universal gas constant.

The ratio between CP and CV is the specific heat ratio, γ.

Γ = CP /CV
