Solution

The correct option is D 15
At 40℃, amount of water vapor in $1 m^{3}$ of air= $45 g$
Also, mass of water vapor present in $1 m^{3}$ of saturated air is $30 g$ at $30 ℃$
So when temperature is decreased to $30 ℃$ , the amount of water vapor that condenses is only $15 g$ .

At 40∘C, the actual amount of water vapour present in 1m3 of air is 45 g. If the temperature decreases to 30∘C, then the amount of water vapour that condenses is _______ g. [Take the mass of water vapour present in 1m3 of saturated air at 30∘C as 30 g].

The correct option is D 15At 40℃, amount of water vapor in 1m3 of air=45gAlso, mass of water vapor present in 1m3 of saturated air is 30g at 30℃So when temperature is decreased to 30℃, the amount of water vapor that condenses is only 15g.
