What phase of matter do molecules have the lowest amount of energy?
The kinetic energy of water molecules in ice is less than the kinetic energy of watermolecules in water and that is less than the kinetic energy of water molecules in stream.That is because the range of temperatures where ice exists, -273C to 0C, is less than the range where water exists, 0C to 100C, which is less than the range where water gas exists, 100C and up. Kinetic energy climbs continuously with temperature through each phase.Kinetic energy is the energy of motion, KE=mv2/2.All molecules have an average kinetic energy proportional to the absolute temperature, particularly, Translational kinetic energy =3kT/2.There is no maximum. Increasing temperature increases molecular kinetic energy until the energy destroys the molecule and then the fragments will have an average kinetic energy 3kT/2.
What happens to the molecules in a glass of water as the water evaporates?
The energy of a molecule is made up of potential and kinetic. so as kinetic increases, potential decreases. Also as when molecule is in gaseous state, the distance between molecules is much greater than that in a liquid, so the potential energy is less as a gas NOTE a molecule has potential energy when it is a certain distance away from its equilibrium position between adjacent particles during its vibrations in a liquid. Kinetic energy is motion energy. SO in there is less attraction between adjacent molecules, so potential energy is less.
When water boils some of its molecules have enough what to overcome the attraction of neighboring molecules?
kinetic energy
Why does it take a lot of energy to change the temperature of water to make it vaporize?
Liquid water has an unusually high specific heatcapacity. It is one of the highest of any substance known. But, that's just another way of saying that it is hard to change water's temperature--it doesn't explain why water has a high heat capacity.Thermal energy is stored in liquid water as kinetic energy (molecular motion and rotation), as kinetic and potential energy in the vibrations of the inter-atomic bonds and, in particular, as kinetic and potential energy in the vibrations of the hydrogen bonds between molecules (H2O is a polar molecule with very strong hydrogen bonds). Much of the thermal energy that goes into water is stored as potential energyand, since temperature is a measure of only the average kinetic energy of the molecules, doesn't contribute to raising its temperature.
When a substance is heated it must gain electrons and energy?
Yes, it gains kinetic energy, for instance, when water is heated into water vapours the molecules of water vapour move faster than the molecules of water. This is because the water vapour has more kinetic energy than water.

What happens to the average kinetic energy of the water molecules in your body when you have a fever?
The average kinetic energy of water molecules goes up. Fevers cause the internal temperature to rise which increases kinetic energies.
If a bathtub and a cup contain water at the same temperature which will have more thermal energy?
-- Temperature is the direct observation of the average kinetic energy of themolecules in the substance.-- If the tub of water and cup of water have the same temperature, then theaverage kinetic energy of the molecules in each one must be the same.-- The tub full of molecules needs more total energy than the cup of molecules does,in order to average the same for each molecule.
How does the water warm up?
Thermal energy applied to the water is transformed into kinetic energy by the water molecules. The water molecules have more energy so the temperature increases.
Does a cup that has warm water has the same kinetic energy as a cup that has cold water in it?
No. The molecules of hot water contain greater kinetic/thermodynamic energy.
Which are faster cold water molecules or hot water molecules?
Of course, hot water molecules, having more kinetic energy.
When water boils some of its molecules have enough what to overcome the attraction of neighboring molecules?
kinetic energy
By increasing the temperature the temperature of water how are you changing the kinetic energy of the water molecules?
It is being increased, because temperature is the average kinetic energy of the object.
Does water always have the same energy?
No. The energy you might be referring to is kinetic energy which is the energy possessed by individual water molecules. An increase in kinetic energy will be percieved as and increase in temperature. Similarly a decrease in kinetic energy will be percieved as a decrease in temperature.
In which phase do water molecules have the highest kinetic energy?
vapour/steam
The average kinetic energy of water molecules is greatest in .?
Steam at 100C
