The door of a working refrigerator is left open in a well insulated room. The temperature of air in the room will

Options

  1. Adecrease
  2. Bincrease in winters and decrease in summers
  3. Cremain the same
  4. Dincrease

Correct answer

D. increase

Step-by-step solution

In a refrigerator, the heat dissipated in the atmosphere is more than that taken from the cooling chamber, therefore the room is heated. If the door of a refrigerator is kept open.
