According to Boyle's Law, pressure and volume have an inverse relationship when temperature is held constant. This means that as the volume of a gas decreases, the pressure increases, and vice versa.
If the volume of a gas is increased at a constant temperature, the pressure will decrease. Similarly, if the volume is decreased, the pressure will increase.
No, if the volume of a gas is held constant, the pressure cannot change. This is because the gas molecules are not able to move or expand to create more or less pressure.
If the volume of a gas is doubled at a constant temperature, the pressure will be halved. This is because the same number of gas molecules are now occupying a larger space, resulting in a decrease in pressure.
When the volume of a gas decreases, the same amount of gas molecules are now occupying a smaller space. This leads to more frequent collisions between molecules and the walls of the container, resulting in an increase in pressure.
