Which of the following is NOT a reversible process?

Options

  1. AMelting of ice
  2. BConduction of heat
  3. CIsothermal expansion of gas
  4. DAdiabatic expansion of gas

Correct answer

B. Conduction of heat

Step-by-step solution

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.
