the answer is false. but i don't know why. can anyone explain?

The answer is false.. because all the molecules gain heat energy... which is transfered to kinetic energy in the electrons... the heat energy is transfered to kinetic energy in the molecules only when the water reaches the boiling tempreature...

I think the keys words in play here are,
"all", and "MUST".
These are very restrictive words in a True/False question.
Temperature is the measure of the average kinetic energy of the particles of a system. When the temperature of an object increase, on average, the particles making up that object experience an increase in kinetic energy.
The key word here is "average".
It is possible for the temperature of some object to increase by only a few of its molecule's gaining kinetic energy since this would change the average KE value and thus the temperature.
It is theoretically possible for the temperature of the water in the glass in increase without "all" of the molecules gaining KE, making the statement false.

False.
Temperature is based on the average kinetic energy of all the water molecules. So, if the temp rises, that simply means, in the average, the energy rose. Like any average, based on a distribution, there will be some molecules that have increased energy, but there will be some that have not increased their energy. Some might even have lost the energy they initially had.

False, temperature is related to the average kinetic energy of molecules. Increasing temperature means the average kinetic energy is increasing, but nothing can be said about the kinetic energy of individual molecules.

the only time an energy increase is potential is during a phase change. There are probably a few molecules on the surface that are in the process of a phase change, which would be where some would be potential. just a guess.

The asnwerrs here seem to be thorough enough, so just to reiterate, In a true false question, the words all and mut typically mean the answer is false. almost nothing in biology or physics happens 100% of the time.

False, the energy is almost never distributed equally. Look up the Boltzmann distribution.
