Matter Flashcards pt.2
Any characteristic that can be observed using your 5 senses without changing the substance
Physical properties
Any characteristic that describes how matter interacts with another substance
Chemical properties
The characteristic of having all 9 features of living things
Biological propety
Change to the physical properties of matter, substance is not changed into a new substance
Physical change
Change to the chemical properties of matter, substance is changed into a new substance with new properties, cannot change back
Chemical change
Matter cannot be created nor destroyed,
The number of atoms/mass of the reactants equals the number of atoms/mass of the products.
Law of Conversation of Matter/Mass
🚩solid, liquid, and gas
🚩Changed by changing temperature or pressure
Phase/State of Matter
🚩Definite shape & Definite volume
🚩Particles packed together and vibrate but have fixed position
🚩Lower energy
Solid
🚩Has no definite shape but has definite volume
🚩Particles spread apart
🚩Medium energy
Liquid
🚩No definite shape & no definite volume
🚩Particles spread far apart
🚩High energy
Gas
🚩matter changing from solid to liquid
🚩⬆ energy, ⬆ particle movement
🚩melting point= temperature substance melts at
Melting
🚩matter changing from liquid to solid
🚩⬇ energy, ⬇ particle movement
🚩freezing point= temperature substance freezes at
Freezing/Solidification
🚩matter changing from liquid to gas
🚩⬆ energy, ⬆ particle movement
🚩Boiling point= temperature substance turns to gas at
Vaporization/Evaporation
🚩matter changing from gas to liquid
🚩⬇ energy, ⬇ particle movement
Condensation
🚩matter changing from solid to gas
🚩⬆ energy, ⬆ particle movement
Sublimation
