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
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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

C Correct answer
Explanation

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

Multiple choice chemistry matter in our surroundings diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

On heating matter, the particles ...... energy and on cooling matter, the particles .......energy.

  1. lose, gain

  2. gain, lose

  3. lose, lose

  4. gain, gain

B Correct answer
Explanation

On the heating matter, the kinetic energy of particles increases, so they gain energy and on the cooling matter, the particle's the motion of particles decreases, so they lose energy.

On cooling a gas, potential energy stored is released in the form of:

  1. mechanical energy

  2. kinetic energy

  3. heat energy

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

On cooling a gas, the temperature falls down and the stored potential energy is released in the form of heat energy so that the temperature fall and the gas becomes cool.

The phenomenon of change from one state of matter to another and then back to the original state is called ___________.

  1. changing the state of matter

  2. inter-conversion of states of matter

  3. converting the state of matter

  4. all of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The phenomenon of change from one state of matter to another and then back to the original state is called the inter-conversion of states of matter.
