when pressure goes up
|
volume goes down
|
|
|
when volume goes up
|
pressure goes down
|
|
|
first person to do a systematic quantitative study of the pressure-volume relationship was the Anglo-Irish 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 temperature-volume 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 Gay-Lussac
|
|
|
states that the pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant
|
Gay-Lussac's Law
|
|
|
because Gay-Lussac's law involves direct proportions, the ratios are
|
equal at constant volume
|
|
|
P1/T1 = P2/T2
|
Gay-Lussac'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
|
