Which of the following is NOT a reversible process?
- A Melting of ice
- B Conduction of heat
- C Isothermal expansion of gas
- D Adiabatic expansion of gas
Answer & Solution
Correct Answer
(B) Conduction of heat
Step-by-step Solution
Detailed explanation
A temperature gradient is a physical quantity that describes in which direction and at what rate the temperature changes in a specific location. Temperature always flows from the hottest to coldest source, due to the fact that cold is nothing but the absence of heat energy.
