Question

The ratio of specific heat capacity at constant volume to that at constant pressure for an ideal gas is found to be equal to
The degrees of freedom for the ideal gas
3
would be
O 3
4
o 7
O 5​

Answer 1

Answer:

The ratio of the specific heats is 5/3 for monatomic ideal gas and 7/5 for diatomic gas. Its value for air is 1.4. This ratio is used to define (1) adiabatic process pVγ=const p V γ = const , and (2) speed of sound in gases v=√γRT/M v = γ R T / M .
