D: It absorbs energy from the environment.
E: It rises upward.
F: It sinks downward.

Respuesta :

Answer:

The answers are options B,D and E

Explanation:

B) The particles in the liquid are slowly overcoming the forces of attraction and spreading out due to the thermal energy they are absorbing. This makes the liquid less dense as it slowly changes into a gas after reaching its boiling point.

D) The particles start absorbing the energy form the surroundings as latent heat of evaporation. They need this energy to overcome the strong forces of attraction between particles to change into the gaseous state

E) The particles have spaced out due to the thermal energy absorbed, making the liquid lighter and it rises upwards.
