Chemical Thermodynamics Question 137

Question: The work done during the expansion of a gas from a volume of 4dm3 to 6dm3 against a constant external pressure of 3atm is ( 1L,atm,=101.32,J ) [CBSE PMT 2004]

Options:

A) + 304 J

B) -304 J

C) - 6 J

D) -608 J

Show Answer

Answer:

Correct Answer: D

Solution:

W=pΔV ; W=3×(64)

W=6×101.32 ( ,1,L,atm,=101.32,J ) W=608,J
