when pressure goes up

volume goes down


when volume goes up

pressure goes down


first person to do a systematic quantitative study of the pressurevolume relationship was the AngloIrish chemist named

Robert Boyle


(1662) states that for a given mass of gas at constant temperature, the volume of the gas varies inversely with pressure

Boyle's law


the product of the two variable quantities is constant in an

inverse relationship


the product of ______ and _______ of at any two sets of conditions is always constant at a given temperature

pressure, volume


P1 x V1 = P2 x V2

Boyle's law


in 1787 the french physicist and balloonist _________ _________ investigated the quantitiatve effect of temperature on the volume of a gas at constant pressure

Jacques Charles


increase in volume of a gas with an

increase in temperature


decrease in volume of a gas with

decrease of temperature


the temperaturevolume relationship for any gas can be measured only over a limited range because

at low temperatures gases condense to form liquids


from his quantitative studies, Charles observed that at constant pressure, the graph of gas volume versus temperature yields a

straight line


zero volume equals

273.15*C


the temperature at which the average kinetic energy of gas particles would theoretically be zero

absolute zero


who established the absolute zero scale in 1848

Kelvin (William Thomson)


states that the volume of a fixed mass of gas is directly proportional to its kelvin temperature if it's presure is kept constant

Charles's Law


the ratio of the two quantities that change is a constant in a _______ relationship

direct


V1/T1 = V2/T2

Charles's Law


the graph of a relationship such as Charles's Law that is direct proportion is a

straight line


on a hot summer day, the pressure in a car tire

decreases


the increase illustrates a relationship that was discovered in 1802 by a French chemist named

Joseph GayLussac


states that the pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant

GayLussac's Law


because GayLussac's law involves direct proportions, the ratios are

equal at constant volume


P1/T1 = P2/T2

GayLussac's law


combines the three gas laws

combined gas law


P1 x V1/T1 = P2 x V2/T2

combined gas law


the combined gas law enables you to do caculations for situations in which

none of the variables are constant
