Question

1 mole of a monoatomic gas undergoes the pro-
cess PT = constant. Then the molar heat capac-
ity of the gas during the process will be equal to
(1) 4R A
(2) 2.5R
(3) 3.5 R
(4) 8R/3
ans is 2 please explain in brief​

Answer 1

Answer:

PV∗= constant (Polytropic process)

Heat capacity in polytropic process is given by

[C=CV+1−xR]

Given that PV3=constant⇒x=3   ......(1)

Also gas is monoatomic so CV=23R   .......(2)

By formula

HOPE IT HELPS YOU

=23R+1−3R=23R−2R=R
