Explanation:
Answer:
D) liquid and gas
Explanation:
The three main states of matter are:
- Solid: in solids, the molecules are bond together by strong intermolecular forces, so the molecules are not free to move. Therefore, a solid has a definite shape, so it does not take the shape of its container.
- Liquid: in liquids, molecules are not bond together, so they are free to move (still, there are some weak intermolecular forces which keep them close to each other). Since in liquids molecules can slide past each other, they take the shape of the container.
- Gas: in gases, molecules are totally free to move, so gases take the shape (and also the volume) of the container.
Based on the definitions above, we can conclude that the correct answer is
D) liquid and gas
