A good year blimp (a huge airship) is filled to a volume of 1,800L at a temperature of 35°C. As
the weather changed the blimp is then cooled
at constant pressure to a temperature of -46°C.
What is the final volume of the blimp?

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
