An ideal gas is expanding such that PT³ = constant. The coefficient of volume expansion of the gas is :

Accepted Answer

PT³ = constant

(\frac{n R T}{v})

T³ = constant

T⁴ V^{$-$ 1} = constant

T⁴ = kV

\Rightarrow 4 \frac{Δ T}{T} = \frac{Δ V}{V}

....... (1)

Δ

V = V

γ

Δ

T ........ (2)

comparing (1) and (2), we get

γ = \frac{4}{T}
