Hi:) how does boiling point of a liquid affect the rate of evaporation?

The temperature at which a liquid's vapor pressure is equal to the liquid's surrounding pressure, which motivate liquid to transform into vapor is understood as Boiling Point. While evaporization is observed on a liquid's surface as it transitions into the gas phase. The accompanying gas must not be saturated with the content which evaporates.

The evaporation and boiling point have inverse relationship, which showcase that more is the boiling point of any liquid, thus lesser will be its rate of evaporation. A substance with powerful inter-molecular bonds requires more energy to crack these bonds, and is therefore defined as high boiling point liquid or non-volatile as it is not feasible to evaporate spontaneously, as with rubbing alcohol.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
