In a Carnot's engine, as the gas gives heat energy to the sink, then the temperature of the sink

In a Carnot's engine, as the gas gives heat energy to the sink, then the temperature of the sink
  1. increases
  2. decreases
  3. remains constant
  4. becomes zero

Solution

In carnot engine, sink is thermal energy reservoir hence as heat is rejected or extracted, temperature does not change.
