Chapter 10 And 11 Flashcards
When are real gases most like ideal gases
At high temperature and low pressure
When do the properties of a real gas vary?
When they are polar
Properties of gases
Can expand Have fluidity Low density Compressible Can diffuse and effuse
What is diffuse
Spontaneous mixing of two substances
What is effuse
Passing through a tiny hole
F -> C
5/9 (F - 32)
C -> F
(9/5 • C) + 32
How many mm in an ATM
760mm
How many cm in an ATM
76cm
How many inches in an ATM
29.92in
How many kPa in an ATM
101.3kPa
How many torr in an ATM
760torr
How many psi in an ATM
14.7lb/in^2
On a mountain what happens trying to boil water to cook food
Water boiling point decreases, not as hot, food takes longer to cook
Boyle’s law
At constant temperature, the volume of a gas is inversely proportional to it’s pressure
P•V
Charle’s law
At constant pressure the volume of a gas is directly proportional to it’s kelvin temperature
V/T where T is in kelvin
Gay-Lussac’s law
At constant volume, the pressure is directly proportional to the Kelvin temperature
P/T
Equal volumes of gases at same temp and pressure contain the same what
Number of molecules
Avagadro’s law
Equal volumes of gases at same temp and pressure contain equal numbers of molecules
V/n = K where n is number of molecules
Dalton’s law
The sum of the partial pressures are equal to the total pressure
