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, gas
-Changed y changing temperature or pressure
Solid
-Definite shape and definite Volume
-Particals packed together and vibrate but have fixed positions
-lower energy
Liquid
-No definite shape but has definite volume
-Particals spread apart
-High energy
Gas
-No definite shape and no definite volume
-Particals spread far apart
-High energy
Melting
-Matter changing from solid to liquid
-energy, partical movement
- Melting point=temperature substance melts at
Freezing/solidification
-matter changing from liquid to solid
-energy,partical movement
-freezing point= temperature substance freezes at
Vaporation
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
