The molecules of which form of water have the highest kinetic energy?
Out of the three states of matter, gaseous phase has always maximum kinetic energy...so water molecules also possess the highest kinetic energy in gaseous phase that is in the steam form. We have to give energy to liquid water to make water vapour and this energy goes as kinetic energy of molecules.
And also we can observe that gas occupy all the volume available to it. This is also possible due to kinetic energy.

When an ice cube is dropped into a cup of hot coffee, the heat flows from _________.
Heat is the transfer of thermal energy between that are at different temperatures. Energy is always transferred from the warmer object(which has a higher temperature) to the cooler one(which has lower temperature). Similarly, molecules with a lot of energy move faster than molecules with smaller amount of energy, thus causing the former to have more heat.
For example, an ice cube in a glass of water eventually melts.This is because, the heat from the water, which is warmer, flows to ice cube until both are at the same temperature, and therefore no ice cube is left.
