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

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 change back

Question 6

Law of Conservation of Matter/Mass

Answer 6

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

Question 7

rPhase/State of matter
solid,
Definite shape & definite volume
Particles packed together and vibrate but have fixed positions
Lower energy
Liquid
No definite shape but has definite volume
Particles spread apart
Medium energy
Gas
No definite shape & no definite volume
Particles spread far apart
High energy
Melting

matter changing from solid to liquid
⬆ energy, ⬆ particle movement
melting point= temperature substance melts at
Freezing/ Solidification
matter changing from liquid to solid
⬇ energy, ⬇ particle movement
freezing point= temperature substance freezes at
Vaporization/Evaporation
matter changing from liquid to gas
⬆ energy, ⬆ particle movement
Boiling point= temperature substance turns to gas at
Condensation
matter changing from gas to liquid
⬇ energy, ⬇ particle movement

Sublimation
matter changing from solid to gas
⬆ energy, ⬆ particle movement
Deposition
matter changing from gas to solid
⬇ energy, ⬇ particle movement

Answer 7

liquid, and gas
Changed by changing temperature or pressure
Solid
