Use the Ideal Gas Law:
PV=nRT
V=nRT/P
If temperature and pressure were both doubled, it is clear that
V=nR(2T)/(2P)
Thus, the doubling would cancel out, and the volume would remain unchanged.

What would the volume of the gas be if the temperature doubled and the pressure stayed the same? In: http://wiki.answers.com/Q/FAQ/2543-873[Edit categories]
Nothing. In a closed system, only the pressure will change. Also, pressure depends on the gas and the actual temperature the gas is at now (I.e -10 Kelvin doubled = -20 K).
You need to read up on the various pressure laws and constants in thermal dynamics (ie Boyles Law, Charles' thereom).
the volume would remain the same due to the combined gas law. For example
100 ml of gas when p and t are doubled equals what?
(P1xV1)/T1 = (P2xV2)/T2
P1 and T1 are timed by 2...
(1x100)/1=(2x ? )/2
cross multiply and you will find that ?=100
You tell me
The volume of the gas is halved.
if kelvin temp is halved, the volume is halved if pressure is constant.
Because kelvin temperature has a simple relationship with volume, according to Charles's' law if the kelvin temperature becomes doubled at constant pressure the volume of the gas also becomes doubled, this relation is not with Celsius or Fahrenheit temperature.
pV = nRT we can firstly assume that n (number of moles) and R (gas constant) do not change and as pressure is also kept constant, the temperature must be proportional to the volume. Thus if temperature is increased from 27C (300K) to 327C (600K) and is doubled, the volume must also double.
half
The pressure of a gas would be reduced by half if the volume of the container doubled, provided that no other change occurred. Pressure and volume are inversely proportional. The relationship between the two is known as Boyle's law. In brief, the volume of a gas changes inversely with the pressure of the gas if the temperature and quantity of gas remain constant.
if kelvin temp is halved, the volume is halved if pressure is constant.
The pressure is decreased to 50 %.
For the pressure to remain the same, the temperature would double if the volume also doubled.
If you let it expand until the new pressure is the same as the original pressure, then the volume will be doubled. But if you want, you could restrict it to stay in the same volume as before. It could do that, but the pressure would double.
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.
Charles Law (also known as the law of volumes) describes how gases tend to expand or contract with temperature changes.If the temperature changes and the gas molecules and pressure remains the same then the volume will increase or decrease at the same rate that the temperature changes.Since the temperature doubled the volume will double to 6L.
Because kelvin temperature has a simple relationship with volume, according to Charles's' law if the kelvin temperature becomes doubled at constant pressure the volume of the gas also becomes doubled, this relation is not with Celsius or Fahrenheit temperature.
volume, temperature and mass
The initial pressure is halved. Use Boyle's law that relates pressure & volume at a constant temperature. P1V1 = P2V2 In this case the V1(initial volume) is doubled so V2 = 2V1 P2 = P1V1/V2 = P1V1/2V1 P2 = (1/2)*P1
.. thenEITHER the pressure is halved for the same amount (moles) of gas,ORthe amount (moles) of gas is doubled at the same pressure,ORany valid combination of these possibillities.
pV = nRT we can firstly assume that n (number of moles) and R (gas constant) do not change and as pressure is also kept constant, the temperature must be proportional to the volume. Thus if temperature is increased from 27C (300K) to 327C (600K) and is doubled, the volume must also double.
Gases Boyle's law states that the Volume of a given amount of gas at constant Temperature varies inversely proportional to Pressure. You have a given volume of gas, and you double its pressure keeping Temperature constant, the volume will reduce by half.
