Across
- 4. a characteristic that can be observed (intensive), such as texture, color, odor, melting point, boiling point, density, or measured (extensive) such as mass, length, volume, that is used to describe matter and can be observed or measured without changing its composition
- 5. the property or power of conducting heat, electricity, or sound
- 6. a chemical reaction; a process that changes substances into new substances
- 8. the ability of a chemical to burn or ignite, causing fire or combustion
- 10. the temperature at which a solid turns into a liquid
- 12. a chemical reaction in which oxygen combines with another substance; for example, when metal rusts
- 14. an object's mass divided by its volume; a measure of how many particles are packed together into a certain amount of space
- 15. solid particles that have been separated from a solution
Down
- 1. the amount of a substance (solute) that will dissolve in another substance (solvent) at a certain volume and temperature
- 2. a characteristic of a substance that is measurable or observable during a chemical reaction; includes pH, heat of combustion, reactivity
- 3. the ability of a material to be beaten into a thin sheet or to be shaped without breaking
- 5. wearing away due to chemical reactions, mainly oxidation. It occurs whenever a gas or liquid chemically attacks an exposed surface, often a metal, and is accelerated by warm temperatures and by acids and salts
- 7. a change in matter that does not affect its chemical composition
- 9. the temperature at which a liquid changes into a gas
- 11. the relative capacity of an atom, molecule, or radical to undergo a chemical reaction with another atom, molecule, or compound
- 13. the ability of a material to be stretched into a wire without breaking
