Q: You find a clear substance that has a definite shape. What form of matter is the substance?

A: Solid (Is this right)

Yes.

Yes, you are correct. A clear substance that has a definite shape would be in the solid state of matter. Solids are characterized by having a fixed shape and volume, and their particles are tightly packed together in an ordered arrangement. To identify the form of matter, you can observe the properties and behavior of the substance based on its physical state, which can be determined by factors such as temperature and pressure.
