Real vs Ideal
100
Gases move from an area of high concentration to an area of low concentration.
What is diffusion?
100
10 diameters
How far apart are gas molecules?
100
At constant pressure, the volume will go down if the temperature goes down.
What is Charles' law?
100
100. ml of gas are enclosed in a cylinder under pressure of 760. mm Hg. What would the volume of the gas be at a pressure of 1520 mm Hg?
What is 50.0 ml?
100
particles will experience some force of attraction
What is real gas?
200
Gas particles hit the walls of their container
What is pressure?
200
Explains pressure and brownian motion
What is constant rapid motion of molecules?
200
smaller molecules diffuse faster
What is Graham's law?
200
The density of a gas at STP is 2.42 g/L. What is it's gram formula mass?
What is 54.2 g?
200
weak attraction that occurs as a result of temporary dipoles
What is van der Waals force?
300
the property of gas that allows a squeezed gas' volume to be reduced
What is compressibility?
300
All energy lost by one molecule is gained by another
What is an elastic collision?
300
P1 * V1 = P2 * V2
What is Boyle's law?
300
A certain gas occupies a volume of 100. ml at a temperature of 20. C. What will its volume be at 10. C, if the pressure remain constant?
What is 96.6 ml?
300
the lowest temperature at which a substance may exist as a gas at atmospheric pressure
What is condensation temperature?
400
Volume is volume of container.
What is expansion?
400
Because gas particles are so far apart and move so fast
How come gas particles are not attracted to one another?
400
The total pressure is a result of the sum of the partial pressures.
What is Dalton's Law?
400
Calculate the pressure required to compress 2 L of a gas at 700. mm pressure and 20.C into a container of 0.1 L capacity at a temperature of -150 C.
What is 6000 mm Hg?
400
van der Waals, dipole-dipole, hydrogen bonds
What are intermolecular forces?
500
1/1000
What is density of a gas?
500
Caused kinetic energy to increase and therefore more collisions with particles and container occurred
What is raise the temperature?
500
the relationship between volume and temperature as described by Boyle's law
What is inversely proportional?
500
An unknown quantity of gas at a pressure of 3.3 atm has a volume of 2.6 L and a temperature of 93 C. How many moles of gas are present?
What is .29 mol?
500
high temperatures and low pressures
