Question

A diatomic gas is given heat of 700 J at constant pressure, the work done by the gas is??​

Answer 1

Explanation:

Suppose the volume changes from V

1

to V

2

and the temperature changes from T

1

to T

2

.

The heat supplied at

ΔQ=ΔU+PΔV=ΔU+nRΔT=ΔU+

f

2ΔU

[ΔU=

2

nfRΔT

]

The change in internal energy is

ΔQ=ΔU[1+

f

2

]

105=ΔU[1+

5

2

]⇒ΔU=75J

sorry bro I know only for 105 u can use this technique
