A typical phase change diagram is shown below. What are the correct names of the numbered arrows?
1 – solid, 2 – liquid, 3 – vapor, 4 – gas
1 – gas, 2 – vapor, 3 – liquid, 4 – solid
1 – freezing, 2 – melting, 3 – condensation, 4 – vaporization
1 – melting, 2 – freezing, 3 – vaporization, 4 – condensation

The correct answer is option 3 i.e. 1 – freezing, 2 – melting, 3 – condensation, 4 – vaporisation

Take the reference to the phase change diagram attached below:

The process of change of phase from solid to liquid is melting (2) and its reverse i.e liquid to solid is freezing (1)
Similarly, The process of change of phase from liquid to gas is vaporisation (4)and its reverse i.e gas to liquid is condensation (3)

Answer : The correct option is, (1)-freezing, (2)-melting, (3)-condensation, (4)-vaporization

Explanation :

As there are three states of matter which are solid, liquid and gas. And there are four phase changes processes which are melting, freezing, vaporization and condensation.

Melting process : It is a process in which the phase changes from solid to liquid state.

Freezing process : It is a process in which the phase changes from liquid to solid state.

Vaporization process : It is a process in which the phase changes from liquid to gaseous state.

Condensation process : It is a process in which the phase changes from gas to liquid state.

The phase diagram are shown below.
