Question

A gas is heated first keeping the pressure cons-
tant and then keeping the volume constant
through the same range of temperature. Heat
supplied in the first process to that of supplied
in the second process is

1) More
2) Less
3) Equal
4) More or Less

please explain answer clearly friends..​

Answer 1

Explanation:

Heat added at constant volume is equal to the change in internal energy of the system.

Change in internal energy ΔU=nC

v

ΔT

For ΔT=150K, ΔU=Q

v

=6300 J

∴ 6300=nC

v

(150) .........(1)

Let the change in internal energy be ΔU for ΔT=300K

∴ ΔU=nC

v

(300) .........(2)

Dividing (2) and (1) we get

6300

ΔU

=

150

300

⟹ΔU=12600 J
