Question

A diatomic gas is heated at constant pressure. The fraction of heat energy use to increase the
internal energy is​

Answer 1

Answer:

we know that ΔU= nC_{v} ΔT

and ΔQ=nC_{p} ΔT

where C_{v} = 5R/2

and C_{p} = 7R/2 ( For a diatomic gas)

Hence ,  fraction of heat energy used = ΔU/ΔQ

And that is 5/7.
