What will be the specific heats of helium at constant volume and constant pressure? `gamma` of helium = `1.667, R = 8.318 xx 10^(7) erg cdot mol^(-1) cdot^(@)C^(-1)`,
`J = 4.18 xx 10^(7) erg cdot cal^(-1)` and molecular mass of helium = 4.

Text Solution

Verified by Experts

The correct Answer is:
`c_(v) = 0.746 cal cdot g^(-1) cdot^(@)C^(-1), c_(p) = 1.243 cal cdot g^(-1) cdot^(@)C^(-1)`
