During an isothermal expansion, a confined ideal gas does –150 J of work against its surroundings. This implies that
-
- 150 J heat has been removed from the gas
- 300 J of heat has been added to the gas
- no heat is transferred because the process is isothermal
- 150 J of heat has been added to the gas
- (a) or (d)
Correct Option: E
If a process is expansion then work done is positive so answer will be (a).
But in question work done by gas is given –150J so that according to it answer will be (d).
