The freon at 30 km absorbs the sun's UV light that otherwise would photodissociate O 2 . Freon absorbs infrared radiation from the earth and thus heats the ozone, causing it to dissociate. None of the above. The answer depends upon the molecular weight. This was done to illustrate that a.
Gases condense into liquids at very low temperature.
The van der Waals equation of state gives a more accurate value for the volume V at low temperature. The volume of a fixed number of moles of gas at constant atmospheric pressure will decrease as T decreases . Rubber freezes and breaks at low temperature. Warm air has higher kinetic energy and thus is more buoyant. There are fewer molecular aggregates in warm air.
