The pressure will increase.
volume increases
If the volume stays the same, the pressure will decrease.
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.
When the pressure of a gas is decreased, the gas molecules move farther apart, leading to an increase in volume. This can cause the gas to expand and fill a larger space. Additionally, decreasing pressure can also lower the temperature of the gas due to the reduced number of molecular collisions.
It will start to smell. The volume will increase.
volume increases
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.
It goes up (assuming all other conditions are constant) Learn the universal gas law, seriously, it's not that hard.
Dry ice is a solid form of any gas
