Water is made up of many molecules that are in constant, random motion. These molecules collide with each other to gain or lose kinetic energy from or to other molecules. The molecules nearer to the surface of the water and have high enough kinetic energy will be able to change from liquid to gaseous state. Since the molecules with higher kinetic energy have moved out of the water, the average kinetic energy of the water drops which inturns means that the temperature of water will drop as well.
the particles start to move because they are warming up, this makes the particles less dense and able to move even more because the particles are moving, and moving particles Generate heat. this makes the particles move further apart and change state from a liquid to a gas
An evaporating liquid is cooling down because the most energetic molecules are escaping into the gas phase. Therefore, the molecules remaining in the liquid state have less average kinetic energy.
"For molecules of a liquid to evaporate, they must be located near the surface, be moving in the proper direction, and have sufficientkinetic energy to overcome liquid-phase intermolecular forces. When only a small proportion of the molecules meet these criteria, the rate of evaporation is low. Since the kinetic energy of a molecule is proportional to its temperature, evaporation proceeds more quickly at higher temperatures. As the faster-moving molecules escape, the remaining molecules have lower average kinetic energy, and the temperature of the liquid decreases. This phenomenon is also calledevaporative cooling."

basically the kinectic energy will turn into molecules and when touching a cold surface will cause it to create steam. Does this help?
The highest velocity molecules are lost.

The kinetic energy content increases and the speed of its particles increases.
thermal
Two gasses at the same temperature have the same amount of average kinetic energy per molecule. Since an oxygen molecule has about 16 times the mass of a hydrogen molecule, it must move faster than a hydrogen molecule with the same kinetic energy. This is based on the equation KE=1/2MV2
Kinetic energy is energy related to movement. The formula is (1/2) mass times velocity squared. Potential energy is energy of position. The formula for gravitional potential energy is mgh (mass times gravitation times height).
Then that molecule will escape the surface of the liquid and become a molecule of gas. This is the process by which water slowly evaporates even when not heated.
The kinetic energy of a single gas molecule is not proportional to anything. The average kinetic energy of gas molecules is proportional to their absolute temperature.
The kinetic energy of a single gas molecule is not proportional to anything. The average kinetic energy of gas molecules is proportional to their absolute temperature.
kinetic
Average Kinetic Energy is determined by the temperate of the gas. The higher the temperature, the higher the average kinetic energy of the gas molecules.Total Kinetic Energy is the average kinetic energy multiplied by the mass - the number of gas molecules in the box.- DENNIS LAM
Kinetic energy of gas molecules is proportional to temperature.
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.
In vibration and spin.
The kinetic energy of a molecule can in better words be known as the kinetic energy which makes up 68% of its state of matter.
increases
Kinetic energy. That's energy related to the movement of objects, the "energy of movement".
temperature is the measure of a molecule's average kinetic energy, so yes.
