The internal energy of a system remains constant when it undergoes -
(a) a cyclic process
(b) an isothermal process
(c) an adiabatic process
(d) any process in which heat released by the system is equal to the work done on the system.
Choose the correct statements :-
Options
- Aa, b, c
- Bb,c
- Ca, b
- Da,b,d
Correct answer
D. a,b,d
Step-by-step solution
In a cyclic process (\mathrm{dU}=0 \Rightarrow \mathrm{U} \rightarrow) constant
In an isothermal process (\mathrm{dU}=0)
(\Rightarrow \mathrm{U} \rightarrow \text{ constant })
If (\Delta Q=\Delta \omega) means (d U=0 \Rightarrow U \rightarrow) constant
