Question

If a substance is in the gas phase, which of qualities of the gas will stay constant?

Answer 1

Answer:

Mass is the right answer

Explanation:

Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy. The particles move very fast and collide into one another, causing them to diffuse, or spread out, until they are evenly distributed throughout the volume of the container.

Therefore the only constant property about matter in a gas state is its mass!

Answer 2

Volume - hope this helps (:
