Question

When wax is heated, it turns into a liquid. How are the wax molecules affected by this change of state?
A. The Molecules Gain Energy
B. The Molecules Lose Energy
C. The Molecules Move Closer To One Another
D. The Space Between The Molecules Increases
E. The Space Between The Molecules Decreases
(there are 2 answers)

Answer 1

Answer:

Option A and Option D

Explanation:

Wax is a solid substance , and its molecules are tightly packed together ....when wax is heated the molecules of wax gets kinetic energy and move about randomly and tell the inter molecular forces binding them together is broken and the fact turn into the liquid . In the liquid state the molecules have more free moment so the spread out and distances between them increases . so, when the wax is heated the kinetic energy to overcome the inter molecular bond in the solid and the distances between the molecules increase in the liquid state!
