how will you show that gas does not have a definite volume
Answers
Assume we have a colorful, non-poisonous gas to arrange a demonstration with.
Keep the gas contained in a transparent (say glass or clear plastic, depending on the reactivity of the gas) vessel with a closed valve leading via any kind of tubing or hose (preferably also transparent) to an identical or any available sized other transparent container.
What do you expect will happen when the valve is opened?
Suppose you have “n” such identical additional vessels all connected to the first in either 1) series or 2) a star layout and you open all valves to all vessels from the first. What do you think you will observe happening to the gas contained formerly in the first container? Will it choose to occupy just two of the “n” containers? Three? …. All???
Would you expect to see the same density of the gas in all containers? How long should it take for the new system configuration to reach equilibrium? What is equilibrium in these circumstances?
Is the volume of the gas dependent on the shape (and total volume) of the vessels?
(Unless you can safely react it with another gas, before allowing it to dissipate….. don’t use chlorine gas!! —- even though the color is easily visible… or iodine! … even better in color! Or the brownish nitrogen-oxygen containing simple molecular gas!)
Sorry bro,
Gas always has a fixed volume depending upon the size and shape of object holding its shape changes
