When the temperature is constant gas volume will decrease as the pressure decreases is that true?

If I remember correctly it is a little more complicated than that. The general equation PV=nRT for an ideal gas is elementary knowledge. The fact is that when you increase temperature many things can happen. It depends on how you treat your system. In general if you increase temperature in an open system the pressure will remain fairly constant, but the volume will increase. If it is a closed system in which the volume is not allowed to expand the pressure will increase with increased temperature. You also have to remember chemical properties also such as phase changes. Hope that rambling mess helps lol.

∙ 13y agoThe Standard Gas Law; PV=nrt shows, by inspection, if no other variable changes, pressure decrease will result in temperature decrease. And, of course, vice versa.
It's important to note that this is not valid in the free atmosphere because this assumes a constant volume. In reality, when air warms, volume increases and pressure will remain the same.

What happens when you decrease the temperature of a gas?
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.
What will cause a decrease in a gas pressure in a closed container?
A loss of gas, or a decrease in temperature.
The pressure of gas decreases with increasing temperature?
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.
What can you say about pressure and volume according to boyles law?
For a given mass at constant temperature, the pressure time tghe volume is a constant. pV=C
What are the effects of temperature and volume of gas samples at constant pressure?
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.
When the temperature of a gas is constant will the volume increase or decrease as the pressure decreases?
as the pressure decreases the volume of gas increases at constant temperature
When the temperature is constant will the the volume of a gas decrease as the pressure decreases?
At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.
If the temperature of gas in the container decreases what happens to its pressure?
Assuming the volume is kept constant, the pressure will also decrease in this case.
When the temperature is constant the volume of a gas will decrease as the pressure decreases. true or false?
False, see Boyle's law
When temperature of a gas decreases at constant volume it?
...pressure decreases.
When the temperature of a gas decreases a constant volume its?
...pressure decreases.
When the temperature of a gas at constant volume decreases it's?
...pressure decreases.
Does a decrease in temperature results in a decrease or in crease in the volume of gas?
Temperature is directly proportional to volume i.e. as temperature increases volume of gas also increases and as it decreases, the volume also decreases
What happens to kinetic energy of gas particles as temperature decreases at a constant pressure?
kinetic energy increases with the increase in temperature is a postulate in kinetic molecular theory of matter.if the pressure is kept constant when temperature decreases the kinetic energy of the molecules decreases resulting in decrease in the volume of the gas. Charle's Law state's that For a given mass of dry gas at constant pressure ,volume is directionally proportional to temperature ie V~T
What happens to the pressure of a gas if the volume increases?
It will increase? No it will decrease when the same amount of gas is held at constant temperature.
When the temperature of of gas increases at constant pressure its?
As pressure increases, if temperature is constant, the gas will decrease in volume.
What happens when you decrease the temperature of a gas?
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.
