Question

A monoatomic gas at 27°C is compressed adiabatically to 8 / 27 of its original volume. The rise in temperature will be

(a) 300°C 

(b) 350°C 

(c) 375°C 

(d) 400°C

Answer 1

Correct option: (c) 375°C

Explanation;

Ratio of specific heats for mono atomic gas,

Hence, rise in temperature = T₂ – T₁ = 402 – 27 = 375ºC
