Anu wanted to find out which solid, marbles or beads, occupy more space. In order to be a fair test what things should be kept same?

  1. Amount of liquid

  2. Size of the container

  3. Number of marbles and beads

  4. Mass and volume of the marbles and beads
Reveal answer Fill a bubble to check yourself
A,B,C Correct answer
Explanation

A matter is something that has mass and occupies space. Both marbles and beads are matter since they have mass and occupy space. In order to measure which one occupies more space, the amount of liquid, size of the container and number of marbles and beads are required. The amount of liquid displaced by the solid will be the space occupied by the solid. Higher the displaced volume, higher the space occupied. Since space occupied is independent of mass and hence D is incorrect

Which of the following statements about water are correct?

  1. Water has a fixed mass

  2. Water can be compressed

  3. Water takes the shape of its container

  4. Water has a fixed volume
Reveal answer Fill a bubble to check yourself
A,C,D Correct answer
Explanation

Water is a liquid hence it will show all the properties of liquids, it can take the shape of container, it has fixed mass and volume and very less compressible.


Hence the correct options are A, C and D.

Water is liquid at room temperature. Which of the following is the correct reason to justify it?

  1. In water, the inter molecular forces are strong enough to keep its particle bound with each other

  2. The melting point of water is below room temperature

  3. Its boiling point is above room temperature

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The intermolecular force of attraction between the water molecules is strong enough to keep the molecules/particles bound to each other. The melting point of water is below room temperature as it is already present in the liquid state whereas, its boiling point is above room temperature, i.e; $100^oC$ and room temperature is $20^oC - 22^oC$

A table made by iron is solid because:

  1. it has fixed shape because of strong molecular forces.

  2. it can not be deformed easily because of strong molecular forces.

  3. it is metal.

  4. None of these.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The iron table is solid because the intermolecular force of attraction of the iron table is very strong, thus it is rigid and hence cannot be deformed.
