Question

How does a phase change from solid to liquid occur in a substance?

A. Heat energy is released from the substance, weakening the electrical attraction between molecules.

B. Heat energy is released from the substance, strengthening the electrical attraction between molecules.

C. Heat energy is added to the substance, weakening the electrical attraction between molecules.

D. Heat energy is added to the substance, strengthening the electrical attraction between molecules.

Answer 1

Answer:

see below

Explanation:

1. Heat energy is added to the substance, weakening the electrical attraction between molecules.

2. Both the melting point and boiling point are lower.

3. dipole

4. Water and ethanol have different molecular structures.

5. The lone pairs of electrons in the oxygen atom causes the molecule to be bent; the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges.

Answer 2

Heat is a form factor that changes the solid from light to light to gaseous mediums. The phases take place in a cyclic manner.

• The solid to liquid changes take place due to the melting or fusion, solid to gas take lace through the sublimation, liquid to gas is by vaporization, and gas to liquid is condensation.

• Thus the heat is added and leads to the weakening of the electrical attraction within the molecules.

Hence the correct option is C.
