Question

Which best explains why a crystal is incompressible?

Its molecules remain in position without vibrating.
The molecules of a crystal behave like those of a gas.
There is little, if any, space left between its adjacent molecules.
Its molecules switch positions when they are compressed.

Answer 1

The correct answer is C. There is little, if any, space left between its adjacent molecules.

Step-by-step explanation:

A crystal is incompressible because the molecules or atoms in a crystal lattice are arranged in a tightly packed, repeating pattern with little or no space between them. This means that when pressure is applied to the crystal, the distance between the molecules or atoms cannot be reduced, and the crystal cannot be compressed.

In contrast, gases have a lot of empty space between their molecules and can be easily compressed. Therefore, option C is the correct answer.
