Properties Of Matter

Question 1

Describe some examples of physical properties?

Answer 1

Odor
Color
Size

Question 2

What is matter?

Answer 2

Anything that has mass or volume

Question 3

State what mass is, what instrument is used to measure it, and what units are used?

Answer 3

Mass - the number of molecules in something, balance scale and grams

Question 4

State what weight is, what instrument is used to measure it, and what units are used?

Answer 4

Weight - gravitational pull, spring scale and newtons & pounds

Question 5

State what volume is, what instrument is used to measure it, and what units are used?

Answer 5

Volume - the size of an object, centimeter tape and 1 centimeter cubed or 1 milliliter

Question 6

State what density is, what instrument is used to measure it, and what units are used?

Answer 6

Density - the amount of mass in volume,

Question 7

How are mass and weight different?

Answer 7

Weight is the gravitational pull on an object and weight is the amount of matter in an object.

Question 8

Name the three (3) states of matter?

Answer 8

Solid
Liquid
Gas

Question 9

Describe Solid?

Answer 9

Definite shape, definite volume and particles do not move.

Question 10

Describe Liquid?

Answer 10

No definite shape, definite volume and partial slide by each other.

Question 11

Describe Gas?

Answer 11

No definite shape, no definite volume and particles move freely.

Question 12

For each phase change be able to indicate if heat/energy is put in or taken out?

Answer 12

No answer, but know about the phases.

Question 13

What is a chemical property?

Answer 13

The way a substance reacts with other substances.

Question 14

Describe some examples of chemical property?

Answer 14

Flammable
Corrosion
Rust

Question 15

What is a physical change and give specific examples?

Answer 15

When a substance keeps the same chemical property but changes form and it is also reversible.

Example: Ice Melting

Question 16

What is a chemical change and give some specific examples?

Answer 16

When two (2) or more substances react, new substances are formed and the changes are irreversible.

Examples: Crack open and egg and fry it.

Question 17

State the four (4) clues that indicate that a chemical change has taken place?

Answer 17

1. Produces gas (bubbles)
2. Gives off or takes in heat/light
3. Color change
4. Forms a precipitate

Question 18

What is chemical reaction and give a specific example?

Answer 18

Any transformation from one set of chemicals into another set.

Example - Fire

Question 19

Define mixture and give an example?

Answer 19

When two (2) or more substances are combined together.

Example - Fruit salad

Question 20

Define solution and give an example?

Answer 20

Ingredients evenly mixed.

Example - Lemonade

Question 21

Define alloys and give an example?

Answer 21

Mixture of two (2) or more metals.

Example - Stainless Steele

Question 22

How does increasing temperature affect the rate of chemical change and give an example?

Answer 22

Hot air rises so when you put an open ballon over it, the ballon will rise due to the increased temperature of the air.

Example - Tire

Question 23

How does decreasing temperature affect the rate of chemical change and give an example?

Answer 23

Cold air sinks so when you put an object in cold air it will sink, that is the chemical change.

Example - Ballon Experiment
