Question

state the effect of (1)Surface area (2)Nature of the rate of evaporation​

Answer 1

Answer:

The effects of surface area and nature of liquid on the rate of evaporation,are as follows -

• Surface area : We know that the evaporation of the liquid only happens from the outermost surface of that liquid. And that's why ,the rate of evaporation is directly proportional to the surface area of the liquid. Which means a liquid with greater surface area will have greater evaporation rate and vice versa.

• Nature of liquid : There are two types of liquid according to the nature of evaporation.

1) Volatile

2) Non Volatile

Volatile liquids have much higher evaporation rate than the non volatile liquids. Volatile liquid can evaporate in very short amount of time even in the room temperature and the non volatile liquid needs external heat application for evaporation.
