In terms of kinetic energy explain how a molecule in a liquid evaporates?

Answer 1

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.

Answer 2

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

Answer 3

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.

Answer 4

"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."

Answer 5

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

Answer 6

The highest velocity molecules are lost.
