At constant pressure, density of a gas is :

Open in App

Solution

Verified by Toppr

Correct option is B)

Now by ideal gas equation, PV = nRT

So this gives $PV=Mw RT$, where M is the molecular weight

So on putting the value of w, we get

Density, $d=RTPM $

Clearly if pressure is constant, density is inversely proportional to temperature (T)
