no it increases because it has more room to expand
as the pressure decreases the volume of gas increases at constant temperature
You can decrease the pressure. As pressure decreases, volume increases. and vice versa
It would increase.
When Gases expand to fill a large volume the volume will increase and the pressure will decrease
This one is explained in Boyle's Law. It was stated that if the temperature is constant, the pressure is inversely proportional to the volume. Thus, if the pressure increases, the volume decreases. It is also the same as if the pressure decreases, the volume of the gas increases.
I think you meant what happens to the gas particles when the temperature decreases. If the volume of gas is constant(eg in a fixed container), the pressure of the gas will decrease. If the gas is in a container with a variable volume(eg. balloon), the volume of gas will decrease.
Increased pressure causes the gas molecules to come closer together, thus the volume also decreases.
At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.
Temperature is directly proportional to volume i.e. as temperature increases volume of gas also increases and as it decreases, the volume also decreases
Assuming the volume is kept constant, the pressure will also decrease in this case.
If the temperature decreases, the volume is also going to decrease, and if the pressure decreases, the volume is going to increase. So they balance each other out, if they are decreased at the same rate.
