What is the combined gas law derived from?
the combination of Boyle's ,Charles', and Gay- Lussac's gas laws
What is the two kinds of gases compared in the ideal gas law?
real gas vs. ideal gas
If the temperature is constant as the pressure of gas increases what happens to the volume?
volume decreases
If the temperature goes up what does the volume do?
goes up as well
As the temperature of an enclosed gas increases what does the pressure do?
increases
What unit do you always use when dealing with temperature?
Kelvin
What is the ideal gas constant in L-atm/mol-K.
0.08206
the volume of gas varies inversely with what?
pressure
T/F: If the temperature goes up then the volume goes up.
True
The pressure of a gas is directly proportional to_______________ if the volume remains constant.
temperature (in Kelvin!)
What is the scientific formula for the combined gas law?
P1V1/T1=P2V2/T2
What is the scientific formula for the ideal gas law?
PV=nRT
What is the equation for Boyle's Law?
P1 x V1 = P2 x V2
What is the scientific formula for Charles' Law?
V1/T1 = V2/T2
What is the scientific formula for Gay-Lussac's Law?
P1/T1 = P2/T2
Bonus Question!! What class are you in right now? (Need room number for full credit)
Honors Chemistry, Room 108
Name two differences between real and ideal gases
1) real gas molecules have finite size, ideal is just a point with no shape
2) real gas molecules react with other gas molecules, ideal gases are independent and do not react
A balloon contains 30.0 L of helium gas at 103 kPa. What is the volume of the helium when the balloon rises to an altitude where the pressure is only 25.0 kPa?
124 L
If a sample of gas occupies 6.80 L at 325 degrees C, what will its volume be at 25 degrees C if the pressure does not change?
3.39 L
A sample of nitrogen gas has a pressure of 6.58 kPa at 539 K. If the volume does not change, what will the pressure be at 211 K?
2.58 kPa
A gas at 155 kPa and 25 degrees C has an initial volume of 1.00 L. The pressure of the gas increases to 605 kPa as the temperature is raised to 125 degrees C. What is the new volume?
0.34 L
A sample of hydrogen has a volume of 8.56 L at 0 degrees C and 1.5 atm. Calculate the number of moles of hydrogen present in the sample.
0.57 moles
