(1) In Activity 2-1, Activity 2-2, and Activity 2-3, we examine difference in heat transfer when covered, materials are changed, and more material is used. For each case, which one experiences less heat transfer and explain reasons for why.

(2) For Activity 3-2, calculate the rate of heat transfer to the water inside the cup for both cases. Give possible reasons for the difference in the rates from perspective of absorption of radiation energy.
