Which of the following statements is correct concerning the gas phase? a gas expands spontaneously to fill its container. depending on their chemical nature, two or more gases can form either a homogeneous or heterogeneous mixture. the volume of a gas is always less than the volume of its container. when pressure is applied to a gas, its volume increases.

THIS IS THE BEST ANSWER 👇

Gas expands spontaneously to fill its container.

Explanation:

Gas would always spread spontaneously in any container to fill it. Unassisted gas moves to take up the amount of space in which they are placed. Gas molecules become more random and have more kinetic energy to drive their movements from one place to another. Gases would require no energy input to move.

Then the volume of the container would be the same as the volume of the gas occupying it. Also, when gas is pressurized, the volume decreases significantly according to “Boyle’s law”.

Their ingredients would be in one homogeneous mixture in one step. Regardless of any chemical properties of gases, they form homogeneous mixtures.
