If the pressure of gas increases will the volume of gas also increase?

No. The pressure can increase at constant volume or even decreasing volume. The pressure, volume, temperature and amount of gas in a container are all linked. This is expressed using the Ideal Gas Law, which says that PV = nRT. In this equation, P is the pressure, V is the volume, n is the amount of gas (in moles), R is a constant, and T is the temperature (in Kelvin). What the Ideal Gas Law says is that if the pressure goes up, something else much change, but it could be either the volume, the temperature, or the amount of gas. Let me give a few examples. Imagine some gas inside a piston. If you compress the piston, the volume will decrease, and the pressure will increase correspondingly. Now imagine a solid container (like an oxygen tank for Scuba diving for instance). If it is empty and you start filling it with gas, the pressure will increase. In this case the volume is constant, but the amount of gas is increasing ("n" in the PV = nRT equation). Same idea when you pump up your car or bike tires -- the volume changes more than with a metal container, but not much really. For more information, see the links to the left of this answer.

∙ 15y agoYes, when temperature increases the molecules expand and push out against their surroundings, if the molecules are unbound then the matter will increase in volume. If the molecules are contained, then the increase in temperature will result in an inrease of pressure on their container (this is a gas law known as Charles's Law).

∙ 13y agoUsing Boyle's law, P1V1=P2V2, you can see that pressure and volume must be inversely proportional to each other, so when the pressure increases, the volume must decrease. You can also answer this using common sense: if more pressure is applied to a gas, the particles will be pushed closer together, so they will take up less space, so the molar volume of the gas would decrease.

However, if the rate of increase in temperature is greater than the critical rate necessary, in conjunction with the other two rates, then yes.

∙ 11y agoAssuming the gas behaves ideally, and the temperature and number of gas molecules remain constant; the pressure of a gas decreases if the volume of gas is increased.
Ideal gas law: PV=nRT.
An increase in volume must be associated with a decrease in pressure

∙ 15y agoYes , volume will be decreased because density will be increased. We know that density =mass/volume.

Would the volume of a gas increase or decrease if the pressure on the gas increases?
According to the combined gas law, volume and pressure are indirectly related. Therefore, if the pressure of a gas increases, the volume will decrease.
What happens to the temperature if the pressure of a gas increases?
The pressure increases.
As the temperature of a fixed volume of a gas increases the pressure will?
decrease
According to Boyle's Law if the pressure on a gas increases the volume?
That is correct. it's called Charles's law. it shows the connection between a gases temperature and its volume. in order to maintain constant pressure you must increase the volume of the container holding the gas if you increase the temperature of the gas.
How will a pressure increase affect a gaseous system?
According to Boyle's Law of Pressure-Volume Relationship, an increase in the pressure of a gas will decrease it's volume. And according to Charles's Law of Temperature-Pressure Relationship, an increase in pressure causes an increase in temperature.
How can the pressure of a gas increase?
Primarily in two ways. If the volume is decreased, the pressure will increase. Also, if the temperature increases at a constant volume, then the pressure will increase.
If temperature increase and volume remain constant what is pressure?
This is explained by Charle's law. Keeping volume constant, as the temperature increases then the pressure of the gas also increases.
Would the volume of a gas increase or decrease if the pressure on the gas increases?
According to the combined gas law, volume and pressure are indirectly related. Therefore, if the pressure of a gas increases, the volume will decrease.
What happens to the temperature if the pressure of a gas increases?
The pressure increases.
Explain why increasing the temperature of a gas in closed rigid container causes the pressure in the container to increase?
Because the pressure increases The real answer is: Charles's Law. He found that if you increase the temperature of a constant pressure the volume increases also.
What happens to volume as temperature changes?
if volume of a gas increases temperature also increases
As the temperature of a fixed volume of a gas increases the pressure will?
decrease
If a fixed sample of gas increases in temperature it must also do what?
If a fixed volume of gas increases in temperature, it must increase in volume. If the gas is in a closed system, the pressure inside that system increases instead. When the gas increases in volume, it also decreases in pressure, often rising above colder, more dense gas if possible.
What happens to the pressure as the volume changes?
Pressure will decrease with (because it is inversely proportianal to) volume, if (and only if!) temperature is held constant.
What are the impacts of temperature on gas?
The impacts of temperature on gas are manifold. Increase in temperature increases the gas pressure by increasing its volume. It increases the solubility of gas and vice-verse. The viscosity of gas also increases with increase in temperature.
When the pressure of a gas is increases at constant temperature what happens to the volume?
Volume and temperature are directly proportional to each other and so when temperature is increased the volume also increase and vise virsa
Why does vapor pressure increase with an increase in temperature?
PV=nRT where P=pressure, V=volume, n=no. of moles, R=gas constant, T=temperature(K) since volume and the number of moles remain constant, they can be ignored and we can assume:- that P is proportional to T and thus if temperature is increased, pressure will also increase.
