Question

In an isothermal expansion of ideal gas, the work done BY the gas is +500 J. The heat absorbed by the gas is:

Accepted Answer

A. +500 J

Isothermal: ΔU = 0. So ΔU = Q - W
→ 0 = Q - 500 → Q = +500 J. All the work done comes from absorbed heat.

Answer

0

Answer

Cannot determine

Answer
