Two states of matter are described below. state a: cannot be compressed and retains its shape state b: highly compressible which combination of the state and a substance in that state is correct?

Explanation:

Matter is anything that has weight and occupies space.

There are three states of matter which are:

Solids have a patterned order of arrangement. Their molecules are held close together and they vibrate about a fixed position. They cannot be compressed and they retain their shape due to their ordered arrangement.

For state A, the matter being described here is a solid.

Gases have their molecules in constant motion and their molecules far apart. They fill vessels and exerts pressure on the walls of the container They are highly compressible.

For state B, the matter here is a gas.
