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.
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.
In which physical state would a water molecule have the greatest energy?
A water molecule would have the greatest energy in the gas (vapor) state because the molecules are more spread out and have higher kinetic energy compared to the liquid or solid state.
Why do molecules in hot water move faster than in cold water?
The kinetic theory of matter explains that temperature is a measure of the average kinetic energy of molecules in a substance. In hot water, the molecules have higher kinetic energy, leading to faster movement. This is because heat energy is transferred to the molecules, causing them to vibrate and move more rapidly compared to molecules in cold water with lower kinetic energy.
What are the properties of water in all 3 states?
In its solid state (ice), water molecules are arranged in a rigid lattice structure with low kinetic energy. In its liquid state, water molecules are more loosely packed and have higher kinetic energy, allowing for movement and flow. In its gaseous state (water vapor), water molecules have high kinetic energy and are spread out, moving freely and independently.
The average kinetic energy of water molecules is greatest in .?
Steam at 100C

The average kinetic energy of a sample of water molecules is what?
The average kinetic energy of water molecules is directly proportional to the temperature of the water. As the temperature increases, the average kinetic energy of the water molecules increases as well. This energy is a measure of the motion of the molecules, with higher temperatures corresponding to higher average kinetic energies.

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 in your body increases when you have a fever. This increase in kinetic energy is a result of the body's elevated temperature as it tries to fight off an infection.
Beaker A contains water at a temperature of 15 degrees C beaker B contains water at a temperature of 37 degrees C Which beaker contains water molecules that have greater kinetic energy and why?
Beaker A: 15 C Beaker B: 37 C Beaker B contains water molecules that have the greater kinetic energy (on average). Since beaker B is at a higher temperature than beaker A, the water molecules must be moving faster in beaker B than in beaker A (on average). If heat is being applied to the beakers, then the increased amount of heat applied to beaker B is greater, and the heat will cause the water molecules in beaker B to move faster than the water molecules in beaker A (on average). Kinetic energy = (1/2) (mass) (velocity)^2 Since the velocity of the a water molecule in beaker B is on average greater than the velocity of an average water molecule in beaker A, the water in beaker B has a higher kinetic energy.
How fast do molecules move in hot water?
In hot water, molecules move faster than in cold water due to increased kinetic energy. This increased movement causes the molecules to collide more frequently and with higher energy, which contributes to the water's higher temperature.
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.
Which are faster cold water molecules or hot water molecules?
Of course, hot water molecules, having more kinetic energy.
Does a cup that has warm water has the same kinetic energy as a cup that has cold water in it?
No, the cup with warm water will have greater kinetic energy due to the increased molecular motion and higher temperature of the water molecules compared to the cup with cold water. Temperature is a measure of the average kinetic energy of particles in a substance.
