Find an explanation of why the soda cans in the hot Arizona Summer time can explode in your car truck in you leave them there during a full afternoon. (Data: K(Henry) = 1.538 x 104 torr dm3 / g, solubility of CO2 in water = 4.78 x10-2 g / dm3). Normal pressure: 760 torr (just air). Hint: Consider the atmospheric pressure in the hot AZ summer to equal 700 torr.
