Question

Name A,B,C,D,E and F in the following diagram showing change in its state

Answer 1

Based on the diagram showing the changes in the state of matter, here's the identification of the points:

A: Fusion or Melting (Solid → Liquid)

B: Vaporization or Boiling (Liquid → Gas)

C: Condensation (Gas → Liquid)

D: Solidification or Freezing (Liquid → Solid)

E: Sublimation (Solid → Gas)

F: Deposition (Gas → Solid)

Explanation:

A (Solid to Liquid): When heat is added to a solid, it melts and turns into a liquid (fusion/melting).

B (Liquid to Gas): Increasing the heat further causes the liquid to boil and turn into gas (vaporization).

C (Gas to Liquid): When heat is removed from the gas, it condenses and turns into a liquid (condensation).

D (Liquid to Solid): Decreasing the temperature turns the liquid into solid (solidification/freezing).

E (Solid to Gas): A solid turning directly into gas without becoming a liquid in between is called sublimation.

F (Gas to Solid): When a gas turns directly into solid without becoming a liquid, it is called deposition.

This process aligns with the law of conservation of mass and physical changes in matter, as there is no change in the chemical composition during these phase transitions.
