Question

During an isothermal expansion, a confined ideal
gas does -150 J of work against its surroundings.
This implies that
ya) 150 J of heat has been removed from the gas
(6) 300 J of heat has been added to the gas
(c) no heat is transferred because the process is
isothermal
(d) 150 J of heat has been added to the gas. (2011)​

Answer 1

Answer:

During an isothermal expansion, a confined ideal

gas does -150 J of work against its surroundings.

This implies that

ya) 150 J of heat has been removed from the gas

(6) 300 J of heat has been added to the gas

(c) no heat is transferred because the process is

isothermal

(d) 150 J of heat has been added to the gas. (20
