Question

will the cool drinks give more fizz at the top of the hills or at the foot? explain

Answer 1

they give more fizz at top of hills because solubility of gas is low at altitude and hence the carbon dioxide is less soluble in cold drinks at altitude and give more fizz

Answer 2

The cold drinks will give more fizz at the top of the hill , because, the fizz is created due to the excessive pressure released which is sealed inside the bottle for carbonation.

Now, the pressure release procedure's intensity is dependent on external environmental pressure.

When the internal and external pressures are same the procedure will stop.

Now in the hill top the external pressure is very low and that's why the pressure difference is very high which causes a strong fizzing process.
