science (matter)


matter anything that has mass takes up space
volume measure of the size of a body or region in the three-dimensional space L times W times H = V
Density the ratio of the mass of a substance to the volume of the substance
Mass measure of the amount of matter in an object
inertia tendency of an object to resist being moved or if the object is moving to resist a change in speed or direction until an outside force acts on the object
physical properties characteristics of a substance that doesn't envolve chemical change such as density color or hardness
6 different physical properties thermal conductivity, state, density, solubility, ductility, malleability
chemical properties property of matter that describes a substance's ability to change into a new matter that has different properties (ex. wood smoke ashes)
physical change change of matter from one form to another without a change in chemical properties
flammability the ability of a substance to burn
reactivity the ability of two or more substances to combine and form one or more new substances
states of matter solid-shape its in L times W times H = V, liquid-takes shape of its container L times W times H = V, gas-doesn't have a shape or V
temperature measure of how hot or cold something is specifically measure of the average kinetic energy of the particles in an object
pressure amount of force exerted per unite area of a surface
boyle's law law that states that the volume of a gas is inversely proportional to the pressure of a gas when the temp is constant
charle's law law that states that the volume of a gas is directly proportional to the temp of gas when pressure is content
change of state change of a substance from one physical state to another Melting-solid to liquid, Freezing-liquid to solid, Evaporation-liquid to vapor or s=gas, Condensation-gas to liquid, Sublimation-solid to gas
endothermic chemical reaction that requires heat
Exothermic chemical reaction in which heat is real eased to the surroundings
