Choose the correct statement for the work done in the expansion and heat absorbed or released when 5 litres of an ideal gas at 10 atmospheric pressure isothermally expands into vacuum until volume is 15 litres :

Question

YESPYQ · Accepted Answer

Correct answer: c) Work done will be zero and heat will also be zero.. In free expansion against a vacuum, there is no external pressure resisting the expansion, so no work is done (W = 0). Since the process is isothermal for an ideal gas, there is also no net change in internal energy, so the heat exchanged (Q) is zero.
