States of matter: Solids , liquids and gases.

Instead of directly solving your assignment, I will provide you with sufficient information that will help you solve the assignment.

There are three states of matter: solids, liquids and gases (plasma is the fourth state). These states are differentiated based on their unique properties. A solid has a fixed shape & volume, does not flow and cannot be compressed. A liquid in comparison, is incompressible, flows and does not have a fixed shape. A liquid has a fixed volume. A gas does not have a fixed shape or volume, can flow and is compressible.

Using these properties, we can classify any given material. For example, material B (Q 2) flows and has a fixed volume and hence will be classified as a liquid. In comparison, material A is a Gas. You can similarly solve the other parts.

Hope this helps.
