GAS LAWS Flashcards
Graham’s law
Mass and velocity of a gas are inversely proportional
Boyle’s Law
Volume and pressure are inversely proportional to each other.
Charles law
Volume and temperature (in Kelvin) are directly proportional
Gay-Lusaac’s law
Temperature (in Kelvin) and pressure are directly proportional. Volume must be in a rigid container.
Formula for translating Kelvin and degrees Celsius
K = *C + 273.15
Avogadros law
The more moles you have (more atoms, ions, molecules, formula units), the more volume you have.
1 mol = 1 arm (or equivalent) = volume of 22.414 L
An electron is excited when…
It goes from its ground state (normal state) to its excited state (it’s charged state)
When an electron goes from its excited state to its ground state, it gives off energy in the form of…
Electromagnetic energy
Particles can be…
How many atoms in one gas molecule of O ?
2
What is needed for a compound to be a formula unit?
Atoms, ions, molecules, and formula units.
2 atoms
A polyatomic ion or a group 1/2 element matched with a group 16/17 element. Exceptions: ammonia and water. Both are molecules.
Avogadros law
The more moles you have, the greater the volume
Gas density, d = m/v, what is the relationship between volume and density?
Inverse relationship between volume and density
Dalton’s law of partial pressure
Sum of partial pressures equals the pressure in a rigid container
