However, whenever a gas is compressed, it heats up, so the temperature will also increase, unless you are actively cooling the container. This is why when Scuba divers refill their air tanks, the tanks are kept in a water tub with flowing cold water; otherwise, the tanks will heat up.

P = pressure
V = volume
n = number of particles
R = Gas constant
T = temperature
because nRT remains constant in this scenario...
P1V1=P2V2
V2=.5V1
substitute...
P1V1=P2(.5)V1
P1=.5P2
P2=2*P1

Do Gases have a definite shape and volume true or false?
False. Gases in a container take the shape of the container. The volume of a gas increases with temperature and inversely with pressure, except when in a closed container where volume remains the same as the volume of the container and the temperature and pressure will vary.
If the volume of a container of air is reduced?
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.
A gas with a volume of 4.00 L at a pressure of 205 kPa is allowed to expand to a volume of 12.0 L. What is the pressure in the container if the temperature remains constant?
The pressure is 68,3 kPa.
If a container is half filled with a liquid and sealed at room temperature and atmospheric pressure then what happens inside the container?
because the other half is not empty it is filled with gas
Pressure is used to increase the volume of gas?
An increase of the temperature or a decrease of the pressure.

The temperature of a gas in a sealed container changes from 20.0C to 40.0C if the volume remains constant the pressure will change from 660 torr to?
330
If a container is half filled with a liquid and sealed at room temperature and atmospheric pressure then what happens inside the container?
because the other half is not empty it is filled with gas
The number of molecules in a container is tripled and the Kelvin temperature doubled The volume remains unchanged The new pressure will be how many times greater than the original pressure?
half
If you wanted to predict how temperature will effect the volume of a gas what factors must be held constant?
If temperature increases, then pressure increases. Temperature measures the average speed of particles, so if the temperature is high, then the particles are moving quickly and are colliding with other particles more forcefully. Pressure is defined as the force and number of collisions the particles have with the wall of its container. So if the high temperature causes the particles to move quickly, they are going to collide more often with the container, increasing the pressure. This remains true as long as the number of moles (n) remains constant.
If the temperature remains constant what will happen to the pressure of a gas if you decrease the volume of the container that holds the gas Explain?
The pressure of the gas would rise. Explain? OK, Blow up a balloon and tie the end. Decrease volume of the container (step on balloon). Balloon explodes (Pressure rose)
What happens to the pressure if the temperature is increased?
The pressure will increase if the volume remains the same.
What increases the pressure of gas?
If the quantity of the gas, i.e. the weight of the gas, and the volume of it's container remains the same, the Temperature is the only variable left to play with. The higher the Temperature, the higher the pressure will be. If the Volume of the container holding the gas decreases (everything else remaining constant,) the temperature will similarly increase.Remember the equation P x V = nR x T, where P is pressure, V is the volume, T is the absolute temperature, and the factors, nR represent the quantity of the gas.
What happens to a temperature when apply a force to a fluid?
If the fluid was trapt it would be heated by pressure: Like a pressure cooker or the earth's molten core. Otherwise it would just splash about and remain the ambient temperature. The opposite, is like when you use compressed air to clean your computer. While the volume of the container doesn't change the pressure decrease and thus the temperature decreases too. According to Boyle's law pressure and volume fluctuate inversely. But if the volume remains the same, pressure and temperature fluctuate together. Nice and simple: +Positive Pressure = temperature increase+ -Negatve Pressure = temperature decrease- As long as the volume remains the same.
How does the kinetic theory explain the fact that the pressure of a gas in a sealed container remains constant indefinitely provided the volume and temperature are kept constant?
because according to kinetic theory number of collisions exert force per unit area(pressure) so when the temperature is constant along with volume then the same number of collisions are taking place per unit time thats why pressure remains constant....
