4.48 L of an ideal gas at STP requires 12 calories to taise its temperature by `15^@C` at constant volume. What is the `C_p` (in cal) of the gas ?

Text Solution

Verified by Experts

`C_V = (DeltaE)/(nDeltaT)[therefore n = (4.48)/(22.4) = 0.2] = (12)/(0.2xx15) = 4 cal`
`implies C_P = C_V +R = 4+2 = 6 cal`
