Question

MARK THE STATEMENT AS TRUE OR FALSE
1. The intermolecular forces in gases are weaker than in solids
2. Liquids take the shape of the vessel.
3. All the three states of matter cannot be interconverted into one another.
4. The kinetic theory of matter explains the physical difference between solids, liquids and gases
5. During the inter-conversion of states of matter, mass undergoes a change.​

Answer 1

Answer:

1 . True

2 . True

3 . False

4 . I dont know correctly

5 . True

Answer 2

Answer:

1. True

2. True

3. False

4. The kinetic molecular theory of matter states that: ... The average amount of empty space between molecules gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases. There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together.

5. mass of the object has nothing to do with its state but it is just that to change the state of an object having a greater mass,we need to extract or provide an energy in greater amount but no change in mass is involved during change of state.
