Basic Concepts Of Gases Flashcards
Mixture of Gases
Air (via Kinetic molecular theory)
5 properties of Gases
Highly compressible, expands as the temperature increased, flows easily, steeam 1/1000 density of water, Miscible
Def. of Fluid
Flow, no shape, little resistance
Def of Viscosity
Resistance to flow
Mixed with any proportion
Miscible
Inventors of Kinetic Molecular Theory
Clausius, Maxwell, Boltzmann
4 Kinetic Molecular Theory of Gases
Straight line, Seperated large distance, Kelvin is the average, Energy is the same
How many collisions and speed and size
500m/s; 5x10^-8m; 1 billion collisions
Have negligible volume, and no attraction exists between particles
Ideal gas (No intermolecular forces)
Applying pressure and lowering temperature
Real Gases
Properties that describe a gas
Pressure, Volume, Temperature and Amount of Gas (PVTA)
Force per unit area
Pressure
Pressure formula
P= F/A
Pascal measurement
N/m^2
5 measurements of Pressure
MmHg, atm, torr, pounds per sequare inch, pascal
1 atm is equivalent to how many Pascal?

14.7 psi is equivalent to how many atm
1 atm
Pressure exerted by the gas molecules
Atmospheric pressure
Standard atmospheric pressure
One atmosphere
Why atmospheric pressure is greater near the ground thatn at higher altitudes
(A) more air particles at the gorund
(B) Weight of th ecolumn of air
Who invented barometer uni torr inventor
Torricelli
