use the text below to answer the question.
air, steam and the flammable gas in kitchen stoves are all gases. they have atoms that are
spread out and move around freely. a gas does not have a particular shape, mass or volume.
like liquid, a gas will take the shape of its container. if its not in a container, it will spread
out as much as it can.
which of the following is true about gases?
choose one option
a they are rigid and have fixed forms.
b they have will expand to fill the shape of containers.
c their atoms are close together and flow around each other.
d they do not have mass.

Explanation:

• Option A: The text says gas atoms are spread out and move freely, not rigid with fixed forms.
• Option B: The text states "Like liquid, a gas will take the shape of its container. If it's not in a container, it will spread out as much as it can", which means it expands to fill the container.
• Option C: The text says gas atoms are spread out, not close together.
• Option D: The text says "A gas does not have a particular shape, mass or volume" is wrong as gas has mass (though not a particular one in the sense of fixed value easily measured like solids in simple terms, but it has mass as matter has mass).

Answer:

B. They have will expand to fill the shape of containers.
