Answer 1

Explanation:

1.a

2.b

3.c

4.b

these are the answers

Answer 2

1. (a) Vacuum

• Air, common salt, and chalk have mass and occupy space too and hence they are matters.
• Vacuum means emptiness, which clearly means without any matter.

2. (c) Smell of perfume

• Hate is a feeling, a sound is a percept and magnetism is a physical property, hence none of them are matters.
• Sense of smell is not a matter but the smell of anything specific is considered to be a matter.
• Since perfume is a liquid and is a matter, its smell is also considered a matter.

3. (c) Sand, cold drinks, and almonds

• Sand and almonds are solids, cold drinks are liquids.
• All three occupy space and have mass and hence are matters.

4. (a) Steam (Option given in the question is wrong. It is steam and not stream)

• Sand and iron are solids and hence have strong interparticle forces of attraction.
• Liquid water is again a liquid that has a lower interparticle force of attraction than solids.
• Steam is a gas, and gases have the least interparticle forces of attraction because of their loose molecular arrangement.
