Gas Properties and Laws Flashcards
What is an ideal gas?
One with few to no intermolecular attractions between particles
Do ideal gasses have different physical behavior?
No. All ideal gasses have the same physical behavior.
What is pressure?
Force/area
What is a barometer?
A device that uses mercury to measure atmospheric pressure
What is a manometer?
A curved, mercury-filled device that measures gas pressure
1 atm = how many mmHg ?
1 atm = 760 mmHg
1 mmHg = how many torr?
1 mmHg = 1 torr
How are gas pressure and volume related? (Boyle’s Law)
Gas pressure and volume are inversely related when moles and temperature are constant
How is Boyle’s Law represented mathematically?
P1V1 = P2V2
How are gas volume and temperature related? (Charles’s Law)
Gas volume and temperature are directly related at constant moles and pressure. Hotter gas = bigger volume.
How is Charles’s Law represented mathematically?
V1/T1 = V2/T2
How are gas pressure and temperature related? (Amonton’s Law)
Pressure and temperature are directly proportional at fixed amount and volume of gas. Doubling the temperature doubles the volume.
How is Amonton’s Law represented mathematically?
P1/T1 = P2/T2
What does Avogadro’s Law say?
There is a direct relationship between gas moles and volume. Equal gas volumes have an equal number of molecules (at fixed temperature and pressure).
What is the combined gas law?
P1V1/T1 = P2V2/T2
