Which best explains the relationship between evaporation and temperature?
a) a liquid evaporates slower at lower temperatures because the molecules are more spread apart and are not pushed as easily from the liquid’s surface.
b) a liquid evaporates faster at lower temperatures because the attractions are decreased and more particles can escape the surface of the liquid.
c) a liquid evaporates slower at higher temperatures because the vapor pressure of the liquid is higher, so fewer molecules can escape the surface.
d) a liquid evaporates faster at higher temperatures because more particles have a higher speed and can overcome attractions in the liquid.

Option (d) is the correct answer.

Explanation:

Evaporation is a process in which liquid phase of a substance changes into vapor or gaseous phase.

In a liquid, molecules are less tightly held together as compared to solids. Therefore, molecules of a liquid are able to slide past each other. But when a liquid is heated at a high temperature then molecules gain more kinetic energy.

As a result, number of collision increases between the molecules and hence they start to evaporate from the liquid.

Thus, we can conclude that the statement a liquid evaporates faster at higher temperatures because more particles have a higher speed and can overcome attractions in the liquid, best explains the relationship between evaporation and temperature.

t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanatio

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
