Δ W=Δ Q-Δ U=110-40=70 text J

Q. If the heat of 110 J is added to a gaseous system, whose internal energy is 40 J. Then the amount of external work done is

140J

70J

110J

150J

$Δ W = Δ Q - Δ U = 110 - 40 = 70 J$

Q. If the heat of 110 J is added to a gaseous system, whose internal energy is 40 J. Then the amount of external work done is

140J

70J

110J

150J

ΔW=ΔQ−ΔU=110−40=70J

$Δ W = Δ Q - Δ U = 110 - 40 = 70 J$
