Question
Will the cool drinks give more fizz at top of the hills or at the foot? Explain.
Solution
Carbonated cool drinks give more fizz at the foothill because the solubility of gases in liquids decreases with an increase in temperature. At higher altitudes, the temperature is low and the dissolved CO2 will not escape as fizz, whereas at the foothill it does.
