Question

Where does a cool drink give more fizz, at the top of hills or at the foot?

a) Top of hills
b) Foot of hills
c) No difference
d) Depends on the temperature

Answer 1

A cool drink will have more fizz at the top of hills due to the lower atmospheric pressure, resulting in more carbon dioxide being released.

Step-by-step explanation:

The amount of fizz in a cool drink is determined by the amount of dissolved carbon dioxide gas, which is affected by the pressure of the surrounding environment. At the top of hills, the atmospheric pressure is lower compared to the atmospheric pressure at the foot of hills. Since gas solubility in liquids decreases with a reduction in pressure, a cool drink would show more fizz or release more carbon dioxide at higher altitudes. Therefore, the correct answer is (a) Top of hills, as that is where a cool drink would give off more fizz due to the lower atmospheric pressure.
