Question

A gas is at pressure P and temperature T. Coefficient of volume expansion of one mole of gas at constant pressure is –

• A. $\frac{1}{T}$
• B. T
• C. $\frac{1}{T^{2}}$
• D. T²

Answer 1

Answer: (A)

$\frac{1}{T}$

Answer 2

PV = RT Ž PdV = RdT

\ Coefficient of volume expansion

=$\frac{dV}{dT}$= $\frac{R}{PV}$=$\frac{1}{T}$
