Answer #1

Let us remember the ideal gas law

PV=nRT

Pressure of a gas is directly proportional to temperature

The soccer ball has the same volume in winter

But pressure inside the ball decreases due to the low temperatures in the winter.

As the temperature decreases pressure inside the ball decreases so ball is under infltaed.

Why the pressure drops down?

We fill the ball with air which contains moisture (H2O(g)). This moisture get condense inside the ball at low temperature. Total number of collisions between the molecules and the walls decreases. Thus pressure inside the ball get drops down.
