Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Density and pressure/temperature Density is directly proportional to pressure as bonds gets closer so volume decreases and so density increases. And indirectly proportional to temperature as bonds breaks so volume increase thus density. As pressure increases,with temperature constant, density increases Conversely when temperature increases, with pressure constant, density decreases. PV=nRT P = density *T if you take density as constant then P directly proporotional to T
is it applicable to every asepcts?? That's wot I want to knw.. because incase of cyclone low pressure is created at the centre where the temperature is warmer than the surroundings. Thus pressure being low but temperature is higher. And conversely in anticyclones cases. How is this possible then?
When we are using gas law like PV = nRT here except R all are variable so by keeping constant any parameter other relation can be deduced. and when the atmosphere case comes it's like 1 atm pressure on surface of Earth.. if hot temperature removes the gases by increasing it's volume at that place the gases will get out from that place so the pressure will be low due to there is like empty space as we know P = pgh .
