Which of the following is NOT a property of gases? Your
A. They are easy to compress.
B. They expand to fill their containers.
C. They have a definite shape and a definite volume.
D. They occupy far more space than the liquids or solids from which they form.

C

Explanation:

A. As they do not have a given shape and expand to fill the container, modifying the size of the container modifies the space the gas occupies

B. They are nearly free molecules, which means no bound between them, moving fast and freely around the container

C. NOT A PROPERTY. As said before, as there are no bindings between molecules and move freely, they cannot have a fixed size cause they're always on the move.

D. Because they expand to fill the container, it's easy to them to occupy more space than in any other state, as the container is the only thing that defines how much volume they occupy
