What is absolute zero?
Absolute zero is the lowest possible temperature, which is given by zero kelvin, written 0 k.
A change of 1k is a change of what in degree Celsius?
A change of 1*C.
How do you change from degrees Celsius into kelvin?
K = C + 273
What is Boyle's law?
At a constant temperature the pressure p and volume V of a gas are inversely proportional. pV = constant
What is an ideal gas?
A theoretical gas that obeys Boyle's law (and other laws) at all temperatures is called an ideal gas.
What is Charles'Law?
At a constant pressure, the volume V of a gas is directly proportional to its absolute temperature. V/T = constant
What is the Pressure law?
At a constant volume, the pressure p of a gas is directly proportional to its absolute temperature. p/T = constant
Draw a graph of volume vs temperature(k) for an ideal gas.
Draw the graph of pressure vs temperature(k) for an ideal gas.
What is the value of the molar gas constant R?
Its value is 8.31 j mol-1K-1
What is the ideal gas equation?
pV = nRT
How many particles does one mole of gas contain, and what is the name of this value?
6.02 x 1023 , this number is known as Avogadros constant and has the symbol NA.
What is the equation that lets us calculate the number of particles in a mass of gas?
N = nNA
- number of particles is equal to the number of moles mutplied by Avogadros constant.
What is the value of Boltzmann's constant?
1.38 x 10-23 JK-1
What is Boltzmann's constant K equivalent to?
It is equivalent to R/NA - you can think of Boltzmann's constant as the gas constant for one particle of gas, while R is the gas constant for one mole of gas.
What is the equation of state of an ideal gas?
pV = NKt
