[2005]
(a) Transfer of heat by conduction
(b) Transfer of heat by radiation
(c) Isothermal compression
(d) Electrical heating of a nichrome wire
Show Answer
Answer:
Correct Answer: 42.(c)
Solution:
- (c) Isothermal process occur very slowly so it is quasi-static and hence it is reversible.
The conditions for reversibility
- Must take place infinitely slowly
- The temperature of the system must not differ appreciably
- There must be complete absence of dissipative forces such as friction, viscosity, electric resistance, etc.
