Chapter 12- Gas Laws And Kinetic Theory Flashcards
Pressure eq
Pressure = force/ area
Pressure unit
N/m^2 = Pa
Pascal definition
A pascal is the pressure exerted by a force of 1N acting at right angles to an area of 1m^2
A fluid is a substance that can
Flow
Both liquids and gases are
Fluids
Pressure density eq
Pressure= density x g x 🔺h
Pressure on base eq
Weight of column of water / area
Don’t forget to add on the pressure of the _____ in questions
Pressure of the atmosphere
If a liquid is stationary then the pressure must act
Equally in all directions
Boyle’s law
The pressure of a fixed mass of gas is inversely proportional to the volume, provided the temperature is constant
Boyle’s law equations
P~ 1/V
P1V1 = P2V2
If T1=T2
Isothermal def
The same temperature
Charles’ law
The volume of a fixed mass of gas is directly proportional to its absolute temperature provided the pressure is constant
Charles’ law eq
V~T
V1/T1 = V2/T2
Providing P1=P2
Pressure law
The pressure of a fixed mass of gas is directly proportional to its absolute temperature provided the volume is constant
