Question

Given below are some characteristics of a certain type of matter.

i. its particles can move freely and slide past over one another.

ii. Its particles are held together by moderately strong intermolecular force of attraction.

iii. its particles do not have definite position.

Which of the following matter show the given properties?

• A. water
• B. Wooden block
• C. Air
• D. Oxygen

Answer 1

The correct option is A

water

Correct option explanation:- (a) Given characteristics properties are of liquid and water is liquid, so option (a) is correct option.

The liquids have the following characteristic properties:

1. Liquids have a fixed volume but they have no fixed shape and liquids acquires the shape of the vessel.
2. Liquids generally flow easily.
3. Liquids have moderate to high densities.
4. Liquids have interparticle space between them, so can be compressed to some extent.

Incorrect option explanation:-

(b) Wooden block is solid, so solids have different characteristics properties than liquids i.e. it will have fix shape and particles cannot slide over one another. Hence, it incorrect option.

(c) and (d) :- Both options are under gaseous state, and have different characteristics properties as mentioned in the questions,hence both options are incorrect.

Concluding Statement:- Given characteristics properties are of liquid and water is liquid, so option (a) is correct option.
