Answer:
A. Does not have a fixed volume or a fixed shape.
Explanation:
A liquid is matter that has a fixed volume but not a fixed shape. A gas is matter that has neither a fixed volume nor a fixed shape. Like a gas, plasma lacks a fixed volume and shape.
Liquids have a fixed volume but no fixed shape. This is because the particles in a liquid are further apart than the particles in a solid, allowing them to easily slide past each other. Solids have a fixed shape because their molecules are so tightly packed they cannot do much more than vibrate against each other.
You might ask, What is a definite shape?
Any matter that is a solid has a definite shape and a definite volume. The molecules in a solid are in fixed positions and are close together. Although the molecules can still vibrate, they cannot move from one part of the solid to another part. As a result, a solid does not easily change its shape or its volume.
