During the isothermal expansion, a confined ideal gas does (-150) J of work against its surroundings. This means 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
Answer & Solution
Correct Answer
(A) 150 J of heat has been added to the gas
Step-by-step Solution
Detailed explanation
\(\Delta U = 0\) (isothermal process for ideal gas) \(\Delta U = Q - W\)
