The increase of pressure of a given gas is usually a result of a change in the temperature of the gas. An increase in temperature creates a corresponding increase in pressure.

Yes it may be a chemical change but it can also be a physical change. An example of gas forming in a physical change is when you boil a liquid that liquid evaporates and gas is formed!

Yes, because the chemical composition of the gas particles does not change.

Gas under pressure physical or chemical change?

Physical change.


Is formation of gas a chemical or physical change?

Physical, because the gas is still the same gas, just under pressure Some gasses may undergo spontaneous chemical reactions under very high heat and/or pressure. For example ozone under high pressure will fairly rapidly decay into oxygen gas.


How does increasing the density of gas affect its pressure?

By increasing the density of a gas its air pressure will subsequently increase.

Is the pressure of contained neon gas increases as more gas is added to the container a chemical change?

Increased pressure is a physical change, not a chemical change - even if the increase in pressure is itself the result of a chemical process.


Who is law was it that the idea that the volume of a gas increases with increasing temperature provided the pressure does not change?

Is gas under pressure a chemical change or physical?

Gas under pressure is a physical change not a chemical change because the gas is not being affected chemically (atoms are not bonding to other atoms and etc.). Pressure only forces the gas particles to be closer together, possibly reverting them to liquids if the temperature is low enough.
