Question
The internal energy of a system remains constant when it undergoes : -
Options
A.a cyclic process
B.an isothermal process
C.an adiabatic process
D.any process in which the heat given out by the the system is equal to the work done on the system
Solution
Q = ᐃY + W and ᐃU = nCVᐃT
ᐃU can be zero if ᐃT is zero or Q - W is zero
ᐃU can be zero if ᐃT is zero or Q - W is zero
