Question

. When an ideal diatomic gas is heated at
constant pressure, the fraction of heat energy
supplied which is used in doing work to
maintain pressure constant is

1) 5/7

2) 7/2

4) 2/5

37217​

Answer 1

Answer:

answer is 5\7

Explanation:

the desired fraction is :

f = triangle u \triangle Q

=nCv triangle T\nCp triangle T

=Cv\Cp

=1\y

OR

f=5\7

(asy)=7\5

internal energy of the system is 5\7
