Answer:

1- A and B.

2- C and D.

Explanation:

Kindly, see the attached image carefully that shows the analysis of  state changes from solid to liquid to gas at the heating curve of a chemical substance as it undergoes state changes from solid to liquid to gas.

  • The region (A - B) represents the solid state of the chemical substance.
  • The region (B - C) represents the presence of solid and liquid state of the chemical substance.
  • The region (C - D) represents the liquid state of the chemical substance.
  • The region (D - E) represents the presence of liquid and gas state of the chemical substance.
  • The region (E - F) represents the gas state of the chemical substance.

So,

1- The substance is entirely solid between positions,  A and B.

2- Particles of the substance are in the liquid state and are gaining kinetic energy between positions, C and D.
