Matter Part 2 (086)

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

The characteristic of having all 9 features of living things

Question 4

Physical Change

Answer 4

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

Question 5

Chemical Change

Answer 5

Change to the chemical properties of matter ~ Substance is changed into a new substance with new properties ~ Cannot be changed back

Question 6

Law of Conservation of Matter/Mass

Answer 6

Matter cannot be changed nor destroyed ~ The number of atoms / mass of the reactants equals the number of atoms / mass of the products

Question 7

Phase / State of matter

Answer 7

~ Solid, Liquid, and Gas
~ Changed by changing temperature or pressure

Question 8

Solid

Answer 8

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

Question 9

Liquid

Answer 9

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

Question 10

Gas

Answer 10

~ No definite shape and no definite volume
~ Particles spread far apart
~ High energy

Question 11

Melting

Answer 11

~ Matter changing from a solid to a liquid
~ More energy, more partical movement
~ Melting point = temperature substance melts at

Question 12

Freezing / Solidification

Answer 12

~ Matter changing from liquid to solid
~ Lower energy, lower particle movement
~ Freezing point = temperature substance freezes at

Question 13

Vaporization / Evaporation

Answer 13

~ Matter changing from liquid to gas
~ More energy, more particle movement
~ Boiling point = temperature substance turns to gas at

Question 14

Condensation

Answer 14

~ Matter changing from gas to liquid
~ Lower energy, lower particle movement

Question 15

Sublimation

Answer 15

~ Matter changing from solid to gas
~ more energy, more particle movement

Question 16

Deposition

Answer 16

~ Matter changing from gas to solid
~ Lower energy, lower particle movement
