Question

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

Answer 1

Hint: To solve this we must know the various terms that are used for the conversion from one physical state to another. In the given diagram, the interconversion of three states of matter i.e. solid, liquid and gas is shown. Matter can be converted from one state to another by increasing or decreasing temperature and pressure.

Complete step-by-step answer:
In the given diagram, the interconversion of three states of matter i.e. solid, liquid and gas is shown.
We know that by increasing the heat and decreasing the pressure we can convert solid to liquid and liquid to gas. Similarly, by decreasing the heat and increasing the pressure we can convert gas to liquid and liquid to solid.

A is conversion of solid to liquid. When a solid is converted to a liquid by increasing the heat and decreasing the pressure it is known as fusion. Thus, A is fusion.
B is conversion of liquid to gas. When a liquid is converted to a gas by increasing the heat and decreasing the pressure it is known as vaporisation. Thus, B is vaporisation.
C is conversion of gas to liquid. When a gas is converted to a liquid by decreasing the heat and increasing the pressure it is known as condensation. Thus, C is condensation.
D is conversion of liquid to solid. When a liquid is converted to a solid by decreasing the heat and increasing the pressure it is known as solidification. Thus, D is solidification.
E is conversion of solid to gas. When a solid is converted to a gas by increasing the heat and decreasing the pressure it is known as sublimation. Thus, E is sublimation.
F is conversion of gas to solid. When a gas is converted to a solid by decreasing the heat and increasing the pressure it is known as deposition. Thus, F is deposition.

Thus,A-fusion, B-vaporisation, C-condensation, D-solidification, E-sublimation and F-deposition.

Note: Remember the terms fusion, vaporisation, condensation, solidification, sublimation and deposition. Fusion, evaporation and sublimation can be done by increasing in heat and decreasing the pressure. And condensation, solidification and deposition can be done by decreasing the heat and increasing the pressure.
