`5.6` litre of an unknown gas at `NTP` requires 12.5 calorie to raise its temperature by `10^(@)C` at constant volume Calculate
(a) `C_(v)` of gas
(b) atomicity of gas .

Text Solution

Verified by Experts

The correct Answer is:
5
`:. N = (PV)/(RT) = (1xx5.6)/(0.0821 xx273) = 0.25`
Also `q = mSDeltaT`
`12.5 = 0.25 xx C_(v) xx 10`
`c_(v) = 5` calorie .
