On heating liquids, the intermolecular space between molecules:

  1. increases

  2. decreases

  3. remains same

  4. depends on particles


Correct Option: A
Explanation:

On heating liquids, intermolecular space between molecules increases as the particles gain enough kinetic energy to overcome the force of attraction.

On heating solids, the intermolecular space between molecules:

  1. increases

  2. decreases

  3. remains same

  4. depends on particles


Correct Option: A
Explanation:

On heating solids, the intermolecular space between the molecules increases due to the movement of molecules randomly.

Change of solid state into liquid state is known as _____________.

  1. boiling

  2. fusion

  3. division

  4. freezing


Correct Option: B
Explanation:

Change of solid state into liquid state is known as fusion.


Hence the option D is correct.

The temperature at which particles slow down and convert into a solid is known as:

  1. melting point

  2. boiling point

  3. liquefaction point

  4. solidification point


Correct Option: D
Explanation:

The temperature at which particles slow down and convert into a solid is known as solidification point.

On heating a liquid, heat absorbed by its molecules is absorbed and stored in the form of:

  1. potential energy

  2. kinetic energy

  3. vibration energy

  4. all of the above


Correct Option: A
Explanation:

On heating a liquid, heat absorbed by its molecules is absorbed and stored in the form of potential energy.

The solid state formed from gaseous state on cooling is called:

  1. sublimation

  2. compound

  3. sublimate

  4. None of the above


Correct Option: C
Explanation:

The solid formed by directly cooling a gaseous substance through a process of sublimation is known as sublimate.

On heating liquids, the intermolecular attraction:

  1. increases

  2. decreases

  3. remains same

  4. depends on particles


Correct Option: B
Explanation:

On heating liquids, intermolecular attraction decreases as the particles gain enough kinetic energy to overcome the attraction.

What happens to a gas in condensation?

  1. Atoms or molecules break apart

  2. Atoms or molecules move away from each other

  3. Atoms or molecules clump together

  4. None of the above


Correct Option: C
Explanation:

Condensation takes place when the atoms or molecules come together and clump due to increased inter-molecular attraction.

At which temperature, the particles of liquid  get converted into a gas?

  1. Melting point

  2. Boiling point

  3. Freezing point

  4. None of the above


Correct Option: B
Explanation:

At boiling point, the particles of liquid  get converted into a gas.

  1. falls, decreases, increases

  2. rises, increases, decreases

  3. falls, increases, decreases

  4. rises, decreases, increases


Correct Option: C
Explanation:

On cooling gases and liquids, temperature falls intermolecular attraction increases intermolecular space between molecules decreases.
