An ideal gas in a piston-cylinder assembly undergoes an isothermal expansion, doing 500 J of work on its surroundings.
According to the First Law of Thermodynamics, what is the net heat exchange for this process?
- 0 J
- 500 J of heat released by the gas.
- 500 J of heat absorbed by the gas.
- Insufficient information, as the molar heat capacity is needed.
