what is the interrelationship between temperature, pressure &humidity of the air?

when humidity is more temperature is less.
when temperature is more humifity is less .
Temperature, per se’, does not have a pressure. Air temperature, the air pressure, and humidity are independent measures. I think what you are asking is the inter-relationship between air temperature and the relative humidity.
Relative humidity is a measure of the amount of moisture in the air expressed as a percentage of how much moisture the air, at that temperature, can hold.
Warm air can ‘hold’ more moisture than cold air.
At some point, at a given temperature, the air can hold no more moisture. This is at 100% relative humidity.
Unable to hold any more moisture, the atmosphere releases the water in some form, like rain or dew.
The last key concept is the dew point. This is the temperature at which the moisture in the air will condense and fall out.
If you look at a graphical weather forecast that shows the expected temperature and the dew point, you can see where the lines approach each other. The closer the lines are together, the higher the relative humidity.
Hope this helps.
