Question

6. The vibrations of the molecules in a solid become weaker as the temperature rises.
7. Metals have low boiling points because of the presence of weak intermolecular
force of attraction between their constituent particles.
8. During evaporation, the liquid absorbs heat from the surroundings and
causes the cooling in the surroundings.
9. The intermolecular force of attraction is directly proportional to
the intermolecular distance.
10. Solids cannot be compressed easily when pressed.
10. Camphor
C. Write true (T) or false (F) for the following statements.
1. The whole universe is composed of matter in different forms.
2. Kinetic theory of matter helps us to explain the behaviour of matter.
3. The force of attraction between molecules decreases if the molecules come
closer to each other.
4. Solids expand very little on heating.
5. During the melting of ice, the temperature of ice remains steady until all the
ice is melted.​

Answer 1

Answer:

6. The vibrations of the molecules in a solid become weaker as the temperature rises.

7. Metals have low boiling points because of the presence of weak intermolecular

force of attraction between their constituent particles.

8. During evaporation, the liquid absorbs heat from the surroundings and

causes the cooling in the surroundings.

9. The intermolecular force of attraction is directly proportional to

the intermolecular distance.

10. Solids cannot be compressed easily when pressed.

10. Camphor

C. Write true (T) or false (F) for the following statements.

1. The whole universe is composed of matter in different forms.

2. Kinetic theory of matter helps us to explain the behaviour of matter.

3. The force of attraction between molecules decreases if the molecules come

closer to each other.

4. Solids expand very little on heating.

5. During the melting of ice, the temperature of ice remains steady until all the

ice is melted.
