Would volume increase, decrease, or remain the same if a gas was compressed in a cylinder?

Hi. Compression decreases the volume of a gas. Always.

if u compress a gas u increase the pressure so volume will definitely decrease, AND THE MATERIAL OF THE CYLINDER DOES NOT MATTER, EVEN IF IT IS MADE OF STEEL!!! boyle's law states that the volume of a given mass of gas is inversely proportional to pressure provided temperature remains constant. SO AS PRESSURE INCREASES VOLUME DECREASES.
P * V = n * R * T
THIS EQUATION CONFIRMS THAT FACT. U JUST MAKE V THE SUBJECT OF THE FORMULA.
V = (n * R * T)/P
IF n=1 AND R(GAS CONSTANT)=8.314J/K/mol AND AT A GIVEN TEMPERATURE say 20kelvin. just vary the value of pressure,p. and see what happens.

If you are compressing it you are forcing the volume to decrease.
The temperature would in turn increase.
If it's already compressed, past tense, and you let the cylinder sit, it will remain the same.

The cylinder is made of steel, so volume will remain the same.

From P * V = n * R * T (perfect gas law)
P = pressure
V = volume
n = a constant
R = ???
T = temperature
Volume will remain the same because the tank is a rigid structure, but the temperature will increase.

It would decrease.
Since gas takes the shape of it's container, if the container gets smaller, so does the volume of gas in it.
