Matter: PART 2 Flashcards
Physical Properties
Any characteristic that can be observed using your 5 senses without changing the substance.
Chemical Properties
Any characteristic that describes how matter interacts with another substance.
Biological Property
The characteristic of having all 9 features of living things.
Physical Change
Change to the physical properties of matter, substance is not changed into a new substance.
Chemical Change
Change to the chemical properties of matter, substance is changed into a new substance with new properties, cannot change back.
Law of conservation of matter/mass
Matter cannot be created nor destroyed, the number of atoms/mass of the reactants equals the number of atoms/mass of the products.
Phase/state of matter
- solid, liquid, and gas
-changed by changing temperature or pressure
Solid
- define shape and definite volume
- particles packed together and vibrate but have fixed positions
-l ow energy
Liquid
- No definite shape but has definite volume
- Particles packed together and vibrate but have fixed positions.
Gas
- No definite shape and 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
