The gas pressure increases by a factor of 8. The relevant equation is pV = nRT. Since nothing on the right side of this equation changes, the product on the left side must remain constant. The volume is stated to decrease by a factor of 4/0.5 or 8; therefore the pressure must increase by the same factor.
The pressure is doubled.
The pressure is reduced to one third of the original pressure. The pressure will stay the same you are only changing the volume
Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.
if kelvin temp is halved, the volume is halved if pressure is constant.
If pressure is held constant, volume and temperature are directly proportional. That is, as long as pressure is constant, if volume goes up so does temperature, if temperature goes down so does volume. This follows the model V1/T1=V2/T2, with V1 as initial volume, T1 as initial temperature, V2 as final volume, and T2 as final temperature.
This is explained by Charle's law. Keeping volume constant, as the temperature increases then the pressure of the gas also increases.
directly proportional to the Kelvin temperature
If the volume of a container of air is reduced by one half the partial pressure of the oxygen with in the container will be doubled. If the volume of a container of gas is reduced, the pressure inside the container will increase.
pressure decreases
The pressure is reduced to one third of the original pressure. The pressure will stay the same you are only changing the volume

The pressure will increase, proportionally to the decrease in volume. The Gas Law is PV=RT; then PdV + VdP = 0 if the Temperature stays constant.
Gases are highly compressible. So they don't have definite volume and pressure. As volume is reduced for a given mass pressure increases. Also as temperature changes then at constant volume pressure changes considerably. Same way for a constant pressure temperature change brings a change in the volume. Moreover gasses do not have a free surface.

Assuming pressure stays constant, the volume decreases by 25%. PV = nRT.
At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.
Temperature increases as pressure increases.
Increasing the temperature of a gas will increase it's pressure ONLY if the volume is held constant.
