- 29. Multiple Choice
two identical towels are hanging on a clothesline in the sun. One towel is wet: the other is dry. The wet towel feels much cooler than the dry towel because the
dry towel receives more heat energy from the sun
dry towel has more room for heat storage than the wet towel
presence of water in the wet towel requires an additional amount of heat energy to bring about a temperature change
water in the wet towel prevents absorption of heat energy
