In which sample of water do the molecules have the highest average kinetic energy?
(1) 20. mL at 100.°C (3) 60. mL at 60.°C
(2) 40. mL at 80.°C (4) 80. mL at 40.°C

The answer is (1). The question is asking the average kinetic energy. So it does not related with volume. When temperature increases, the kinetic energy will also increase. So the answer should be the highest temperature.
