the volume doubles
If you double the amount of gas in the same volume you will double the pressure.
There are three variables in gas work that go into volume: amount of gas, pressure of gas, temperature of gas. If we double the amount of gas - the moles - and maintain the temperature and pressure, the volume must double.
When the volume of a confined gas is reduced by half at a constant temperature, the pressure of the gas will double according to Boyle's Law. This is because the product of pressure and volume is constant for a given amount of gas at constant temperature. When the volume decreases, the pressure increases to maintain this equilibrium.

Volume decrease.
The pressure will increase.
Volume increases
volume increases
pV = nRT ← General Gas Lawrearranging to solve the pressure gives us:p = nRT/Vdoubling the volume gives: p = nRT/2VThis means that the pressure will be halved.
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
the volume doubles
If the number of moles of a gas doubles at constant pressure and temperature, the volume of the gas will also double according to Avogadro's law. This is because the volume of a gas is directly proportional to the number of moles present.
