Question

Mayers formula for the relation between two principal specific heats $C_P$ and $C_V$ of a gas is given by

• A. $C_V - C_P = R$
• B. $\frac{C_P}{C_V} = R$
• C. $C_P - C_V= R$
• D. $\frac{C_V}{C_P} = R$

Answer 1

Answer: (C)

$C_P - C_V= R$

Answer 2

Mayer's formula is $C _{ p }- C _{ v }= R$. Here $C _{ p }$ is molar specific heat capacity of an ideal gas at constant pressure, $C _{ v }$ is its molar specific heat at constant volume and $R$ is the gas constant.
