Matter Part 2

Question 1

Physical Properties

Answer 1

Any characteristic that can be observed using your 5 senses without changing the substance

Question 2

Chemical Properties

Answer 2

Any characteristic that describes how matter interacts with another substance

Question 3

Biological property

Answer 3

Change to the physical properties of matter, substance is not changed into a new substance

Question 4

Chemical Change

Answer 4

Change to the chemical properties of matter, substance is changed into a new substance with new properties, cannot change back

Question 5

Law of Conservation of Matter/Mass

Answer 5

Matter cannot be created nor destroyed,
The number of atoms/mass of the reactants equals the number of atoms/mass of the products.

Question 6

Phase/State of matter

Answer 6

solid, liquid, and gas
Changed by changing temperature or pressure

Question 7

Solid

Answer 7

Definite shape & definite volume
Particles packed together and vibrate but have fixed positions
Lower energy

Question 8

Liquid

Answer 8

No definite shape but has definite volume
Particles spread apart
Medium energy

Question 9

Gas

Answer 9

No definite shape & no definite volume
Particles spread far apart
High energy

Question 10

Melting

Answer 10

matter changing from solid to liquid
