It decreases.
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.
It will start to smell. The volume will increase.
If the volume stays the same, the pressure will decrease.
According to Boyle's Law, when the volume of a gas is doubled with no change in Kelvin temperature, the pressure of the gas will be halved. This is because pressure and volume are inversely proportional in a gas at constant temperature.

The pressure will increase.
Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.
Temperature and volume vary directly, so if temperature decreases, so does volume. Volume decreases because the measure of the average kinetic energy of the gas particles (temperature) is decreasing also. When that happens, a gas cannot expand, and will decrease.
