text Density =( operatornamemass( w )/ V text olume ( V )) Now by ideal gas equation, PV = nRT So this gives PV =(w/M) R T, where M is the molecular weight So on putting the value of w, we get Density, d =( PM / RT ) Clearly if pressure is constant, density is inversely proportional to temperature (T)

Q. At constant pressure density of a gas is

directly proportional to absolute temparature

inversely proportional to absolute temperature

independent of temparature

directly proportional to square root of absolute temparatute
