Question

On giving equal amount of heat at constant volume to 1 mol of a monoatomic and a diatomic gas the rise in temperature (DT) is more for –

• A. Monoatomic
• B. Diatomic
• C. Same for both
• D. Can not be predicted

Answer 1

Answer: (A)

Monoatomic

Answer 2

(DQ)_V = C_VDT = $\frac{f}{2}$ R DT Ž DT µ $\frac{1}{f}$

Also f_Mono < f_Dia Ž ( DT)_Mono > (DT)_Dia
