- 5. A combination of two or more substances that are not chemically combined
- 9. he substance in which a solute dissolves to produce a homogeneous mixture.
- 13. a state of matter that occurs when a set of atoms is cooled almost to absolute zero in which a statistical description of the positions of the atoms implies that they physically overlap each other and in effect form a single atom

- 1. a change to the physical—as opposed to chemical—properties of a substance
- 2. a substance made up of various types of particles that occupies physical space and has inertia
- 3. a process by which dissolved components, i.e. solutes, form a solution in a solvent
- 4. the phase change of a substance from the liquid state to a solid-state
- 6. happens when one chemical substance is transformed into one or more different substances
- 7. any substance consisting of particles substantially larger than atoms or ordinary molecules but too small to be visible to the unaided eye
- 8. the phase transition in which gas transforms into solid without passing through the liquid phase
- 10. a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity
- 11. change of a solid into a liquid when heat is applied
- 12. a mixture in which the composition is not uniform throughout the mixture
- 18. a physically distinctive form of matter, such as a solid, liquid, gas, or plasma
- 19. conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase
- 20. sample of matter that conforms to the shape of a container in which it is held and acquires a uniform density inside the container
- 21. the process where water vapor becomes liquid
- 23. a heterogeneous mixture of a finely distributed solid in a liquid
- 26. a state of matter that retains its shape and density when not confined
- 28. a substance that cannot be broken down into simpler components by any non-nuclear chemical reaction
