Question 94

Solids maintain a fixed shape, whereas liquids can flow and take the shape of their container.

Which statement explains this difference?

A

Particles in a solid are much larger than particles in a liquid.

B

Particles in a solid are held in fixed positions by strong attractive forces, while particles in a liquid can slide past one another.

C

Particles in a solid have more kinetic energy and move faster than particles in a liquid.

D

The forces of attraction between particles in a solid are weaker than those in a liquid.
