Temperature of an ideal gas increases in...

Temperature of an ideal gas increases in:

A

Adiabatic expansion

B

adiabatic compression

C

Isothermal expansion

D

isobaric expansion

Text Solution

Verified by Experts

The correct Answer is:
B, D
(a) `q = 0 rArr Delta E = W`
Expansion `rArr W = - Ve rArr Delta E lt 0 rArr Delta T lt 0`
(b) `q=0, W gt 0, Delta E = W rarr Delta E gt 0 rArr Delta T gt 0`
(c ) Isothermal `rArr Delta T = 0`
(d) Isobasc expansion `rArr nC_(P) Delta T = nC_(P) Delta T - nR Delta T`
`nR Delta T = nDelta T (C_(P) - C_(v)) gt 0 rArr Delta T gt 0`
