Want this question answered?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.
As thenumber of molecules incresses so does the volume
Directly proportionalWell the reason is:as you usually know, when you increase volume, pressure should decrease.but in a case of constant pressure, as volume increases, well, pressure stays the same.So how does that work? The only reason pressure wouldn't change is if the temperature will increase, allowing molecules of gas to move more rapidly, and therefore creating pressure that stays constant, as the volume increases. (but if you would keep increasing temperature under constant volume, pressure would actually increase).
"Constant pressure" means the pressure must not change.
In a closed system with constant pressure and no input or output of heat, the gas temperature will remain constant. In that same system, if the pressure is increased, then the gas temperature will also increase. If pressure is decreased, then the gas temperature will decrease.
The molecules collide less frequently, which normally coincides with a decrease in temperature.
If the volume is constant, the density does not change with temperature. With increasing temperature there is still the same number of molecules confined to the same volume of space, so no difference in density.
The Avogadro law is: equal volumes of gases have the same number of molecules at constant pressure and temperature.

The constant collision of gas molecules against the inside walls of a container produces pressure which is directly proportional to the number of collisions.
When pressure double, the volume halves. However this is only true if the number of molecules and the temperature are both in a constant state.
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.

Temperature increases as pressure increases.
As pressure increases, if temperature is constant, the gas will decrease in volume.
The product of pressure and volume. Does PV = nRT look familiar? (:
Lowering temperature reduces the energy of atoms and molecules. They move slower on average - sometimes to the point that they will condense from the gas phase to liquid or solid or freeze into stable locations from a liquid. Vibrations and rotations become less energetic. Kinetic energy (the speed at which the particles bounce around) decreases. One noticeable effect of this is that, all else being equal, the pressure of a gas will decrease - or if the pressure is kept constant, the volume will decrease.
