The surface tension and vapour pressure of water at `20^(@)C` is `7.28xx10^(-2)Nm^(-1)` and `2.33xx10^(3)Pa`, respectively. What is the radius of the smallest spherical water droplet which can form without evaporating at `20^(@)C`?

Text Solution

AI Generated Solution

To find the radius of the smallest spherical water droplet that can form without evaporating at \(20^\circ C\), we can use the relationship between surface tension, vapor pressure, and the radius of the droplet. ### Step-by-Step Solution: 1. **Understand the Given Data**: - Surface tension of water, \( S = 7.28 \times 10^{-2} \, \text{N/m} \) - Vapor pressure of water, \( P = 2.33 \times 10^{3} \, \text{Pa} \) ...
