Lab | Questions & Answers | Grade A | 100%
Correct. Portage Learning
1. Water in solid state: Move fast, stay vlose together but dont touch
2. When water is heated it clumps: Together more
3. When water is heated above boiling it: Moves far apart and moves very
fast
4. Solid: Close together in clump in center
5. Liquid: Fill bottom of container
6. Gas: Move all around container
7. When water is cooled the molecules: Only wiggle and not spin
8. Gas:: Molecules are far apart and move a lot
9. Neon and argon are: More dense in solid form
10. Water is weird because: - it's solid form is less dense than it's liquid from
- all 3 states are found at naturally occurring temps on earth
1/8
, 11. Physical change: No bonds are broken or formed. The same substance is
there after the change.
12. Chemical change: The bonds break apart and the atoms rearrange into
new substances with new chemical bonds
13. K: Element symbol
14. Ag: Element symbol
15. 208
PB
82. The 208 is the: Mass number
16. Mass number =: Protons + electrons
17. 208
Pb
82. The 82 is: Atomic number (z)
18. The atomic number is: # of protons in an atom
19. The mass of a proton is: 1 amu
20. The mass of a neutron is: 1 amu
21. The mass of an electron is: .0005amu
