What occurs when the pressure inside a tire increases after air is pumped into it?

When air is pumped into a tire, the volume of the tire remains relatively constant because the tire is a rigid structure. However, as more air is added, the number of air molecules inside the tire increases, leading to an increase in pressure. According to Boyle's law, which states that pressure and volume are inversely related at a constant temperature, an increase in pressure with a fixed volume typically implies that the volume cannot decrease further unless the tire were to begin deflating or performing dynamic changes.

In actuality, if we interpret the choices regarding the behavior of the tire at that moment, the correct answer relates to the tires' ability to maintain its volume while experiencing an increase in pressure. Due to the rigidity of the tire, it does not expand significantly in volume, but the gas pressure does increase. Thus, the true scenario described in the question is that the tire expands slightly but not in such a manner as to decrease in volume or pressure.

This means that the choice relating to volume decreasing does not apply, and it is important to consider the physical properties of gases and the limitation of the tire's structure. The correct interpretation is that the tire's capacity to hold air leads to an increase in internal pressure without the reduction or significant change
