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.

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.
Can you use a physical property of one substance to change matter into another physical state?
Yes, by utilizing a physical property like temperature or pressure, you can change the state of matter of a substance. For example, increasing the temperature of ice (solid) will change it into water (liquid), or increasing the pressure on water vapor (gas) can change it into liquid water.
How does increasing the density of a gas affect the pressure?
By increasing the density of a gas its air pressure will subsequently increase.
What is the result of increasing the volume of gas?
Increasing the volume of a gas the pressure and density decreases.
Does a compressor change kinetic energy into pressure energy?
Yes, a compressor converts mechanical energy into pressure energy by increasing the kinetic energy of a gas or fluid, which in turn raises the pressure within the system. This is achieved by reducing the volume of the gas or fluid, causing it to be compressed and increasing its pressure.
How can you change the solubility of a gas?
By increasing pressure
Gas under pressure physical or chemical change?
Physical change.

What will increase the volume of gas?
Increasing the temperature, increasing the pressure, or adding more gas molecules will increase the volume of gas.
Is gas under pressure a chemical change or physical?
Gas under pressure is a physical change because the substance is still the same type of matter (gas) but its physical properties, such as volume and pressure, have been altered. No new substances are formed during this process.
Is chlorine gas liquefies at - 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at -35 degrees Celsius under normal pressure is a physical change. This is because the change in state from a gas to a liquid does not alter the chemical composition of the substance, only its physical state.
How does increasing the density of a gas affect the 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?
No, the increase in pressure of contained neon gas as more gas is added to the container is a physical change, not a chemical change. This change is due to the gas particles colliding more frequently with the walls of the container, resulting in an increase in pressure without any new substances being formed.
What change would increase the amount of gas able to be dissolved in a given amount of liquid water?
Reducing the temperature and increasing the pressure would increase the solubility of gas in liquid water. This change would allow more gas molecules to dissolve in the water by creating conditions that favor gas dissolution.
How can pressure change the density of solids liquids and gases?
Increasing pressure can compress the particles of a substance closer together, increasing the density of both solids and liquids. In gases, increasing pressure causes the gas particles to come closer together, decreasing the volume and increasing the density.
Who is law was it that the idea that the volume of a gas increases with increasing temperature provided the pressure does not change?
Charles' law
