Science Unit 1

1. the amount of matter in something, measured in grams (g)
5. mixture in which the molecules of one substance known as the solute are dissolved in another substance, known as the solvent.
6. amount of space an object or substance takes up; measured in liters (L) or cubic centimeters
9. compound or element that is the result of a chemical reaction
10. - ability of a substance to dissolve in another substance such as sugar dissolving in water. Also, a measure of the amount of substance that will dissolve in a certain volume
12. matter that has definite shape and volume such as a rock.
14. - ability to do work
17. state State of matter; a distinct form in which substances can exist, including solid, liquid, gas, or plasma.
18. any of the basic units of matter and energy (such as a molecule, atom, proton, electron, or photon)
21. energy – total kinetic energy contained in all the particles of a substance, also called heat energy
23. – The attractive or repulsive force that acts between magnetic materials
24. – the transfer of heat from a warmer substance to a cooler substance through direct contact. Conductor is also a substance that allows electric current to pass through it.

2. ability of a substance to dissolve in another substance, also a measure of a substance such as sugar dissolving in water, also a measure of the amount of a substance that will dissolve in a certain volume of water.
3. general term for the interaction of electrical charges
4. density/specific gravity- the density of a substance compared to the density of water
7. – a substance that does not transfer heat readily, also a substance that does not allow electric current to pass through it
8. - physical material from which something is made, or which has discrete existence
11. - object that attracts ions
13. the amount of mass (g) in each volume (cm3) of a substance or object. Found by diving the mass of the object by its volume. D=m/v
14. change of matter from a liquid state to a gaseous state (vapor)
15. matter that has no definite volume or shape, such as air
16. rest or move on or near the surface of a liquid without sinking
17. properties - physical property that can be observed without changing the composition or identity of the matter
19. go down below the surface of something, especially of a liquid; become submerged
20. the material that all objects are made of. Anything that has mass and takes up space.
22. matter that has a definite volume but not a definite shape, for example water
