#.......As we know from the ideal gas equation-

p/d=RT

It means,

density d can be written as

d=p/RT

where

d=density

p=pressure

R= gas constant

T= absolute temperature

Now it's evident that density is all about what happens to the ratio (p/T).

#...Due to increase in temperature molecular momentum of air molecules will increase thereby increasing the pressure slightly as compared to amount of increase in temperature, so the ratio of p/T becomes less than 1 . Ultimately density will decrease slightly.................#
