Cards in this set: Term fluid Definition flows and has no definite shape Term pressure Definition force divided by surface area Term Archimede's Principle Definition the magnitude of the buoyant force on an object equals the weight of fluid displaced by the object Term plasma Definition gas-like state containing electrons and positively charged ions Term pascal Definition SI standard unit of pressure Term combined gas law Definition for a fixed amount of ideal gas, the pressure times the volume divided by the Kelvin temp. equals a constant Term crystal lattice Definition fixed pattern of particles within a solid Term ideal gas law Definition can be expressed with PV=nRT Term buoyant force Definition upward force on an object immersed in a liquid Term Bernoulli's priniciple Definition as the velocity of a fluid increases, the pressure exerted by the fluid decreases Term thermal expansion Definition when an increase in temp produces an increase in the volume of matter and a decrease in density Term Cohesive forces Definition electromagnetic attractions of particles within a substance for one another Term coefficient of linear expansion Definition equal to the change in length divded by the original length and the change in temp. Term Pascal's Principle Definition a change in pressure at any point on a confined fluid is transmitted undiminished through the fluid Term adhesive forces Definition attractive forces between particles of different substances Term amorphous solid Definition substance with definite volume and shape but no regular crystal structure Term streamlines Definition representations of the flow of fluids around objects Term coefficient of volume expansion Definition equal to the change in volume divided by the original volume and the change in temperature
