At constant volume, Δ V = 0 w = -PΔ V = 0 Δ H = q = 200 J

Q. $200$ joules of heat was supplied to a system at constant volume. It resulted in the increase in temperature of the system from $298$ to $323 K$ . What is the change in internal energy of the system?

$400 J$

$200 J$

$50 J$

$150 J$

At constant volume, $Δ V = 0$
$w = - P Δ V = 0 Δ H = q = 200 J$
