Answer
change in internal energy when pressure is not changed will be 433 J
Work Step by Step
data:
energy transferred in the form of heat = q = 745J
work done by the expansion of the gas ( by the system on the surrounding) = -W = -312 J
to find:
change in internal energy = ΔU =?
formula used:
at constant pressure
ΔU= q + W
solution:
ΔU = 745J - 312J
ΔU = 433J
so change in internal energy when pressure is not changed will be 433 J.
