If pressure remains constant and the volume of a confined gas is doubled, what happens to the pressure?

When the pressure remains constant and the volume of a confined gas is doubled, according to Boyle's Law, which states that pressure is inversely proportional to volume when temperature is constant, the pressure of the gas will not change.

If you double the volume of the gas while keeping the pressure constant, this means the gas particles have more space to move around, which allows them to occupy this larger volume without any increase in pressure. In other words, the relationship outlined by Boyle's Law indicates that if volume increases, pressure should decrease only if pressure were not held constant. Therefore, while the pressure does not decrease in this case, it also does not increase or change since the condition of constant pressure is maintained.

So, under constant pressure, the pressure remains unchanged. The correct conclusion is that the pressure stays the same.
