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
