a device that measures the pressure of a gas or liquid in a vessel


a device for measuring the pressure of the atmosphere

P = gdh

equation for a barometer (the relationship between the pressure P and the height h of a liquid column in a barometer or manometer)

gravity, density, height

what the "gdh" stand for in P=gdh


density units for P=gdh


height units for P=gdh


Will all liquids in a barometer exert the same pressure? (Y/N)

at STP, the molar gas volume is (plus units)

partial pressure

the pressure exerted by a particular gas in a mixture

gas molecules are negligible in size compared to the distance between them, molecules move randomly in straight lines, the forces of attraction or repulsion (intermolecular forces) are negligible except when they collide, collisions are elastic, average kinetic energy is proportional to absolute temperature

state the five postulates, roughly, of the kinetic theory


what rms (in rms molecular speed) stands for

the process by which a gas flows through a small hole in a container

Graham's law of effusion

The rate of effusion of gas molecules from a particular hole is inversely proportional to the square root of the molecular weight of the gas at constant temperature and pressure.


A substitution reaction is a reaction in which part of a reagent molecule is substituted for an ________ atom on a hydrocarbon or hydrocarbon group.

carbon-carbon multiple bond, C-C single bond

An addition reaction is a reaction in which parts of a reagent are added to each carbon atom of a ___________, which then becomes a ____________.

Markownikoff's rule

states that the major product formed by the addition of an unsymmetrical reagent such as H-Cl, H-Br, or H-OH is the one obtained with the H atom of the reagent is added to the carbon atom of the multiple bond that has the most hydrogen atoms.

split down the middle

the prefix iso- means


hydrolysis of an ester in the presence of a base
