During an isothermal expansion, a confin...

During an isothermal expansion, a confined ideal gas does `-150 J` of work aginst its surroundings. This implies that

A

150 J of heat has been added to the gas

B

150 J of heat has been removed from the gas

C

300 J of heat has been added to the gas

D

No heat is transferred because the process is isothermal

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta Q=Delta U+Delta W`
`Delta Q=0-150 J`, Heat has been given by system.
