Pressure LAWS Flashcards
Pressure definition
Pressure = force per unit
- total amount of force exerted by gas molecules on a surface
Push?
Push=force
Important to know about gases
Low density, compressible, mixture of games are ALWAYS homogeneous, fluid
What does pressure difference do?
Gas will flow from an area of high pressure to low pressure when there is a pressure difference. Bigger the pressure difference the stronger the flow of the gas.
How do density and pressure correlate?
Pressure=density
Boyle’s Law
Pressure of gas is inversely proportional to its volume.
- when one increases the other decreases
*constant temperature
Charle’s Law
Volume is directly proportional to temperature
- when one raises the other raises too, visa versa.
*constant pressure
Combined Gas Law
Both pressure and temperature change as long as the amount of gas stays constant
Avogadro’s Law (least important)
Volume is directly proportional to the number of gas molecules
- gas doesn’t matter
Ideal Gas Law
-combination of Boyles, Charles, and avogadros law
Volume of gas is directly proportional to the number of moles of gas and the temperature of the gas is inversely proportional to the pressure of the gas
Mol Fraction
P(–) = n(mols of whatever)/ nT(mols of the total mols)
