Notes 09/12/2023 meant to be played in learn mode (written)

physical properties

a characteristic of a substance; observed without changing composition; mass, volume, density, brittleness, ductility, malleability, conductivity, luster, solubility, color/smell/shape, temperature, melting point, boiling point

composition

what something is made of

physical property

mass

physical property

volume

physical property

density (mass/volume)

physical property

brittleness (a measure of a material's tendency to shatter upon impact, powder-ability)

physical property

ductility (bendability)

physical property

malleability (the ability of a substance to be hammered or beaten into thin sheets)

physical property

conductivity (of electricity)

physical property

luster (the way a mineral reflects light)

physical property

solubility (the ability to dissolve in another substance)

physical property

color/smell/shape

physical property

temperature

physical property

melting point

physical property

boiling point

chemical properties

how substance reacts/changes/combines; creates new substance and changes composition; chemical reactivity, flammability, corrosiveness, toxicity, radioactivity

chemical property

chemical reactivity (ability to participate in chemical reactions)

chemical property

flammability

chemical property

corrosiveness (the ability to gradually break down a substance by chemical means)

chemical property

toxicity (the degree to which a substance is biologically harmful)

chemical property

radioactivity (the ability to decay into other things)

physical changes

change of shape, size, state of matter; NOT IDENTITY; grinding, crushing, ripping, bending, breaking, squishing, melting, boiling, dissolving

physical change

grinding

physical change

crushing

physical change

ripping

physical change

bending

physical change

breaking

physical change

squishing

physical change

melting

physical change

boiling

physical change

dissolving

chemical changes

color change (usually), smell change, bubbles forming (mostly), precipitate, new coating on metal, release or absorption of heat; depends heavily on context

precipitate

a solid that forms and settles out of a liquid mixture

chemical change

color change (usually)

chemical change

smell change

chemical change

precipitate

chemical change

bubbles forming (mostly)

chemical change

new coating on metal

chemical change

release or absorption of heat
