Chapter 10: Gases Flashcards
What is the value for PRESSURE under STP (standard temperature and pressure) conditions?
1 atm
What is the value for TEMPERATURE under STP (standard temperature and pressure) conditions?
273.15 K
What is the volume of 1 mole of gas under STP (standard temperature and pressure) conditions?
22.41 L always
What are two signs that a gas exhibits ideal behavior?
the gas is particularly small and/or the gas is particularly inert
exp. He is more ‘ideal’ than Cl2 or CO2
Are pounds (lbs) a unit for mass or force?
mass
What do pounds convert to?
kg
How many kg are in 1 pound?
0.454
How can you relate density to height (of a fluid) in those barometer and manometer problems?
Pressure = height x density x acceleration d/t gravity
How many torr are in 1 atm?
760
NOT 670!!!!
What condition adjustment (i.e. pressure, temp, volume) causes a real gas to behavior LESS ideally?
Increase in pressure. Increasing pressure makes a real gas act more real/less ideal
How big must a pressure generally be to start facilitating substantive increases in a real gas’ realness?
pressure above 10 atm
How SMALL must a pressure generally be to start facilitating only SMALL increases in a real gas’ realness?
pressure BELOW 10 atm
What is the second condition (other than pressure) that DECREASES the realness/real behavior of a real gas
high temperature
