Pressure and Gas Laws Flashcards
the force of all the gas particle/wall collisions divided by the area of the wall: All gases exert pressure; it is one of the fundamental measurable quantities of this phase of matter
pressure
Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.

The formula of Boyle’s Law
P1V1 = P2V2
an experimental gas law that describes how the pressure of a gas tends to decrease as the volume of the container increases. (The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.)

The formula of Gay Lussac’s Law
P1/T1=P2/T2.
Celsius to Fahrenheit
° F = 9/5 ( ° C) + 32
Celsius to Kelvin
K = ° C + 273 (.15)
pressure unit in SI system
Pascal (Pa)
a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature if the pressure remains constant.
Charles’ Law
formula of charles’ law
V1/T1=V2/T2

a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules.
the total number of atoms or molecules of any gas is directly proportional to the gaseous volume occupied at constant pressure and temperature.
