Question

When a perfume bottle is opened, some liquid changes to gas and the fragrance spreads around the room. Which sentence explains this?
a Gases do not have a definite volume.
b The particles of gases are closely packed.
c The force of attraction between particles in gases is very high.
d Gases are not matter.

Answer 1

I think the correct answer from the choices listed above is option A. When a perfume bottle is opened, some liquid changes to gas and the fragrance spreads around the room. The gas spreads around the room since gases do not  have a definite volume and they only take the volume of the container they are in. Hope this helps.
