_____13. the saltiness of seawater is the result of this property.
_____14. objects float or sink as a result of this property.
_____15. this is the physical form in which a substance exists.
_____16. this type of matter makes up an object and the way it is arranged.
_____17. the breakdown of water to form two gases is the result of this process.
_____18. this is the ability of a substance to resist burning.
_____19. this is the tendency of a substance to resist changes in its motion.
_____20. this is the rate at which a substance conducts heat.
a. thermal conductivity
b. composition
c. nonflammability
d. inertia
e. state of matter
f. solubility
g. reactivity
h. electrolysis
i. ductility
j. density

Explanation:

1. The saltiness of seawater is due to the solubility of salts in water.
2. Objects float or sink based on density - less dense objects float in more dense fluids.
3. State of matter refers to the physical form like solid, liquid, gas.
4. Composition is what makes up an object and its arrangement.
5. Electrolysis is the process that breaks down water into two gases (hydrogen and oxygen).
6. Nonflammability is the ability to resist burning.
7. Inertia is the tendency to resist changes in motion.
8. Thermal conductivity is the rate of heat conduction.

Answer:

1. f. solubility
2. j. density
3. e. state of matter
4. b. composition
5. h. electrolysis
6. c. nonflammability
7. d. inertia
8. a. thermal conductivity
