The weather report reads, "Temperature `20^(@)C:`Relative humidity 100%".What is the dew point?

Text Solution

Verified by Experts

Given, Temperature = `20^@C`
` Relative humidity = 100%`
So the air is saturated at `20^@C`
Dew point is the temperature at which
saturated vapour pressure is equal to
present vapour pressure
So, ` 20^@C` is the dew point .
