2-500 Elements combine to form these.

2-500A What are compounds?

This unit is the smallest amount of a compound one could have.

3-100A What is a molecule ?

3-200 Most compounds form by sharing these subatomic particles.

3-200A What are electrons?

3-300 These type of properties of compounds differ from the elements it is composed of.

3-300A What are chemical properties?

3-400 This type of bond holds together atoms that are sharing valence electrons.

3-400A What is a covalent bond?

3-500 This type of compound forms when positively and negatively charged atoms are attracted to each other.

3-500A What is an ionic compound?

This type of mixture forms when one substance dissolves or completely mixes into another.

4-100A What is a homogeneous mixture (solution)?

4-200 The components of this mixture are not mixed evenly and retain its own properties.

4-200A What is heterogeneous?

4-300 By which means can the components of a mixture be separated?

4-300A What are physical means?

4-400 These are the states of matter on Earth that form mixtures.

4-400A What are solid, liquid & gas?

4-500 This is the most common form of matter found in the Universe.

4-500A What is plasma?

The formula for density is written this way.

5-100A What is D=M/V?

5-200 This is the density of an object if it has a volume of 24 cm 3 and a mass of 2 grams.

5-200A What is 0.08 g/cm 3

5-300 Objects that float on pond water would have a density less than this number.

5-300A What is 1?

5-400 Object A and Object B have the same mass, but Object A has a greater volume. This object is more dense.

5-400A What is Object B?

5-500 This substance is unusual, its density is greater as a liquid than as a solid.

5-500A What is water?

This is the number of physical states of matter that exist in the universe.

6-100A What is 4?

6-200 Atoms in this state of matter rarely switch positions.

6-200A What is solid?

6-300 This state of matter is rarely found on Earth, but is the most common one in the universe.

6-300A What is plasma?

6-400 This occurs when a substance changes from a solid to a gas.

6-400A What is sublimation?

6-500 This is an example of deposition.

6-500A What is frost or snow?

In a kitchen in Denver, boiling water would be hotter or colder than 100 o C?

COLDER (less air Pressure requires less thermal Energy to boil water)
