Question

Question:
1. Define Vapour pressure.
2. Define Surface Tension.


❌no copy paste ❌

Answer 1

1. Vapour pressure can be defined as pressure formed by the vapor of the liquid (or solid) over the surface of the liquid. This pressure is formed in a thermodynamic equilibrium state in a closed container at a certain temperature.

2.the attractive force exerted upon the surface molecules of a liquid by the molecules beneath that tends to draw the surface molecules into the bulk of the liquid and makes the liquid assume the shape having the least surface area

Answer 2

Hey Mate..!!

Here's Your Answer..!!

✨Vapour Pressure-
The pressure of vapour in contact with its liquid or solid form is called Vapour Pressure.

✨Surface Tension-
The tension of the surface film of a liquid caused by the attraction of the particles is called Surface Tension.
