Question

In a cyclic process, the amount of heat given to a system is equal to (A) net increase in internal energy (B) net work done by the system (C) net decrease in internal energy (D) net change in volume

We have heat equation Δ Q=Δ U+Δ W For cyclic process, Δ U=0 So, Δ Q=Δ W So in a cyclic process, the amount of heat given to a system is equal to net work done by the system.

Q. In a cyclic process, the amount of heat given to a system is equal to

net increase in internal energy

net work done by the system

net decrease in internal energy

net change in volume

net change in pressure

We have heat equation
$Δ Q = Δ U + Δ W$
For cyclic process, $Δ U = 0$
So, $Δ Q = Δ W$
So in a cyclic process, the amount of heat given to a system is equal to net work done by the system.
