Question

the kinetic energy of liquids is more than solids

Answer 1

...
...
Because liquids have more flexibility than solid. So it can flow with a great speed

Answer 2

yeah of course, because the liquid molecules possess greater amount of heat energy than solids. The molecules vibrate at a greater rate than solids, thus their amplitude is also larger than solid molecules. More heat energy means that the average kinetic energy of liquids would be higher than solids.

Simple concept...hope it helps...
