Answer 1

Answer:

(ii) is the correct answer!

The coffee and the mug are transferring heat to the surroundings. This transfer of heat occurs from the hot coffee and hot mug to the surrounding air. The fact that the coffee lowers its temperature is a sign that the average Kinetic energy of its particles is decreasing. The coffee is losing energy.
