Question

The following claim was made in the introduction: Evaporation, or vaporization, is a type of phase change that result when liquid molecules have sufficient energy to escape the attractive forces of neighboring liquid molecules to become gas molecules.

1- how does the kinetic energy of the molecules leaving the thermometer compare to the kinetic energy of the molecules that remain on the Kimwipe

Answer 1

Solution-
As we know that the less the velocity of molecule ,the lower the kinetic energy,and also the lower the temperature is.

But all the molecules don't move at the same speed at any temperature,

therefore the average kinetic energy of the molecules of a substance actually measure's the temperature.
