Blog 3 Chemistry

1.Physical property is properties that can be observed and measured without canting the chemical makeup of the substance.

2. Three physical properties of water: density, boiling point & melting point.

3. The density of solid water compares to liquid water because solid water is sold, which most of the time is frozen causing the water to condense. WIth liquid water is is more flowing, and can go everywhere, and not condense.

4. A setting where water is in a solid, a liquid and a gas at the same time when it snows, Because the water is always in the air, the snow is a solid form of the water, and once it hits the ground a liquid form appears.

5.Heterogeneous is when  there are different substances, not uniformed. When water and rocks are mixed. Homogeneous is when it is the same type of substance, uniformed. Lemonade and water.

6.You need to boil it, and which every substance has the lower boiling would be on top.

7.a.suspension

b. Suspension

c.solution

d.solution

e. Colloid

f. Colloid

8.Colloid, because there are such small particles, that the light goes off the particles. LIke the tydnell effect

10.Solution, because it is clear so it can't be colloid, and if there were no particles on the bottom then, it must be two  homogeneous solutions.

11. An element or a compound that is a material with a uniform, definite composition and distinct properties

12.a. Compound

b.Compound

c.Element

d.Element

e.Element

f.Compound
