Matter Pt 2 Flashcards
Physical Properties
Any characteristic that can be observed using your 5 senses without changeing the substance
Chemical Properties
Any characteristic that describs how matter interacts with anther substance
Biological Properties
The Characteristic of having all 9 features of liveing things
Physical change
Change to the physical properties of matter, substance isnot changed into a new sunstance
Chemical change
Change to the chemical properties of matter, subtsance is changed into a new substance with new properites, connot change back
Law of Conversation of Matter/Mass
Matter cannot be created not destroyed, The number of atoms / mass of the of the reactants equals the number of atoms/mass of the products
Phase/ state of matter
- Solid, liquid and gas
-Changed by changing temperature ot pressure
Solid
-Definite shape & definite volume
-Particles packed together and vibrate but have fixed positions
-Lower energy
Liquid
-No definite shape but has definite volume
- 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
