pressure is measured with a _____________


1 atm= ____ mmHg



constant and random

Gasses are made up of tiny atoms molecules that are in _____________ and _____________ motion


(TorF) There are attractive and repulsive forces in gasses

easily compressible
expand to fill any container
low density
exert pressure on their containers
behave ideally at low pressures and high temperatures

what are the 6 properties of gasses?

Boyle's Law

which law states "the volume of gas varies inversely with the pressure exerted by the gas if the number of moles and the temperature of the gas are held constant

Boyles Law


Charles' Law

which law states: "The volume of a gas varies directly with the absolute temperature (k) if pressure and number of moles of gas are constant'


the temperature in Charles' Law must be in what unit>

Charles' Law

Vi / Ti = Vf / Tf

Combined Gas Law

Which Law is "Used when a sample of gas undergoes change involving volume and pressure and temperature at the same time

Combined Gas Law

PiVi / Ti = PfVf / Tf

Avogadro's Law

Which Law states "The relationship between the volume and number of moles of a gas at constant temperature and pressure

Avogadro's Law

Vi / Ni = Vf / Nf

The measure of the attractive forces exerted among molecules at the surface of the liquid


Substances that are added to a liquid to decrease surface tension


The process of conversion of liquid to gas at a temperature too low to boil

Van der Waals Forces

Physical properties of liquids are explained in terms of their intermolecular forces

Attractive forces between polar molecules

What are Dipole-Dipole Interactions?

London Forces

Henry's Law

What law states that the number of moles of gas dissolved in a liquid at a given temperature is proportional to the pressure of that gas in the atmosphere that is in contact with the liquid


________________ is the amount of solute dissolved in a given amount of solution


__________ properties are properties that depend on the concentration of the solute particles rather than the identity of the solute


_______________ is the solute concentration is mole-based units


_________________ is the movement of solvent from a dilute solution to a more concentrated solution through a semipermeable membrane
