A) A
B) B
C) tea will be equally hot in both cups
D) friend's cup
Correct Answer: A
Solution :
The rate of heat loss is proportional to the difference in temperature. The difference of temperature between the tea in cup A and the surrounding is reduced, so it loses less heat, the tea in cup B loses more heat because of large temperature difference. Hence, the tea in cup A will be hotter.You need to login to perform this action.
