MEDIUMMCQ SINGLEIChO (Chemistry Olympiad)Physical ChemistryThermodynamics and ThermochemistryConcept of Heat and Work An ideal gas receives 10 J of heat in a reversible isothermal expansion. Then the work done by the gas:
A.would be more than 10 J
B.10 J✓ Correct
C.would be less than 10 J
D.cannot be determined
Explanation
As per the first law of thermodynamics, q U W, For isothermal reversible expansion, T 0 q W Work Done, W=10 J Thus, the correct option is (b) 10 J
