Question

Complete the statements by writing the number

Answer 1

Answer :

The substance is in the gas phase only in region  → 5

The substance is in both the liquid and the solid  phase in region  → 2

The substance is in only the liquid phase in region  → 3

The melting point is the temperature at region  → 2

The boiling point is the temperature at region → 4

Explanation :

Six phases of substance:

• Melting or fusion : In this process the phase changes from solid state to liquid state at constant temperature.

• Freezing : In this process the phase changes from liquid state to solid state at constant temperature.

• Evaporation : In this process the phase changes from liquid state to gaseous state at constant temperature.

• Condensation : In this process the phase changes from gaseous state to liquid state at constant temperature.

• Sublimation : In this process the phase changes from solid state to gaseous state without passing through the liquid state at constant temperature.

• Deposition : In this process the phase changes from gaseous state to solid state without passing through the liquid state at constant temperature.
