Question

Which statement best describes the process that the diagrams show?
A.) A solid loses kinetic energy to become a liquid and then becomes a gas.
B.) A solid gains kinetic energy to become a liquid and then becomes a gas.
C.) A gas loses kinetic energy to become a liquid and then becomes a solid.
D.) A gas gains kinetic energy to become a liquid and then becomes a solid.

Answer 1

B. This looks like ice turning to water then to steam

Answer 2

Answer is: B.) A solid gains kinetic energy to become a liquid and then becomes a gas.

Stage 2 is melting (from solid to liquid) and Stage 2 is boiling (from liquid to gas).

In solid, molecules are closely packed, stiff and do not changes of shape or volume. Solid object does not take on the shape of its container.

Liquids have definite volume, but no fixed shape.

Gases not have definite volume and fixed shape, it depends on its container.
