A tube of mercury at a room temperature of 22.4 C has a volume of 10.6 mL between the sealed end of the tube and the mercury. The sun rises and shines through a window on the tube and it warms to 27.8 C. If the atmospheric pressure remains constant, what is the new volume between the sealed end of the tube and the mercury?

The size (radius) of an oxygen molecule is about 2.0 Γ10β10m. 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.
