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

1)20. ML at 100.°C

Explanation:

Average kinetic energy is not related with volume.  so increase in temperature will also increase kinetic energy. so this increase means the highest temperature will be a right answer.
