Solution

Q.
The pressure of a gas changes linearly with volume from A to B as shown in the figure. If no heat is supplied to or extracted from the gas, then the change in the internal energy of the gas will be [2023]

1 6 J

2 Zero

3 −4.5 J

4 4.5 J

Ans.
(4)

$As Δ q = 0$

$Δ u = - W$

$W = \int P d V$

$Δ u = - W = 30 \times 10^{3} \times 150 \times 10^{- 6}$

$= 4500 \times 10^{- 3} = 4.5 J$
