Q. In a cyclic process, the amount of heat given to a system is equal to
KEAM
KEAM 2013
Thermodynamics
A
net increase in internal energy
B
net work done by the system
C
net decrease in internal energy
D
net change in volume
E
net change in pressure
Solution:
We have heat equation
$\Delta \,Q=\Delta U+\Delta \,W$
For cyclic process, $\Delta\, U=0$
So, $\Delta\, Q=\Delta \,W$
So in a cyclic process, the amount of heat given to a system is equal to net work done by the system.
