3.6.2.2: Ideal gases Flashcards
What are the Ideal gas laws?
The ideal gas laws are the experimental relationships between pressure (P), volume (V) and temperature (T) of an ideal gas
What do the Ideal gas laws assume?
The Ideal gas laws assume that the mass and the number of molecules of the gas are constant
What does Boyle’s Law state?
If the temperature T of an ideal gas is constant, then the pressure is inversely proportional to the volume of a gas
The relationship between the pressure and volume for a fixed mass of gas at constant temperature can be written as…
P1V1 = P2V2
What are the axis of the Boyle’s Law graph?
P = 1/V
What does Charles’s Law state?
If the pressure P of an ideal gas is constant, then the volume is proportional to the temperature of a gas
The relationship between the volume and temperature for a fixed mass of gas at constant pressure can be written as…
V1/T1 = V2/T2
What is Absolute zero?
The temperature at which the molecules in a substance have zero kinetic energy
0K
-273.15°C
What are the axis for the Charles’s Law graph?
V = T
In the equation PV=nRT, what is ‘n’?
Number of Moles (mol)
The amount of the substance
In the equation PV=NkT, what is ‘N’
Number of Molecules
For Ideal gases Pressure is inversely proportional to what?
Volume
With Ideal gases work done is equal to what?
P x change in volume
What is the definition of Avogadro’s constant?
1 mole of a substance
What is the value of Avogadro’s constant?
6.02X10^23 atoms/molecules
