Physical Science

heat capacity per unit mass

C=q/ m x (change in) T

do not depend on the amout of matter of quantity of the sample, - intensive properties include color, harness, melting point, boiling point, density, ductility

volume, mass, weight, energy, entropy, number of moles - do depend on the amount of matter or quantity of th sample

measure of the gravitation pull of Eart on an object

measure of the amount of space occupied

measure of the amount of mass per unit volume

measure of the ratio of a substance’s density compared to the density of water

form of heat transfer that requries contact

something that can be observed or measure

something that has to be tested scientifically

cohesive, adhesive, hydrophilic, also a good solvent, polar, high specific heat

hydrogen bonds

O, F, N

the charge becomes more positive ( losing electrons)

the charge becomes more negative (gaining electrons)

proteins, nucleic acids and DNA

simple diffusion, facilitated diffusion, and osmosis

particles are transported from areas ofhighter concentration to areas of lower concentration

specific moleculs are transported by a specific carrier protein

diffusion of water from a high concentration of WATER to a low concentration of WATER ( low concentration of particles to a high concentration of particles)

flexible volume/shape, low density, high compressibility, very free molecular motion

volume constant, flexible shape, high density, no compressibility, move past each other freely

definite volume/shape, high density, no compressibility, vibrate around fixed positions
