the volume of gas varies inversely with what?
What is the equation for Boyle's Law
Solve the Problem: A balloon contains 30.0L of helium gas at 103kPa. What is the volume of the helium whenthe balloon rises to an altitude where the pressureis only 25.0kPs?
Charle's Law is the relationship between what?
If the temperature goes up what does the volume do?
T/F If the temperature goes up than the volume goes up
What is the scientific formula for Charle's Law
Solve the Problem: if a sample of gas occupies 6.80L at 325 deg C, what will its volume be at 25 deg C if the pressure does not change?
Guy-Lussac's Law uses the relationship between what two things?
As the temperature of an enclossed gas increases what does the preasure do?
The pressure of a gas is directly proportional to_______________ if the volume remains constant.
What is the scientific formula for Guy-Lussac's Law?

Waht is the scientific formula for the ideal gas law?
name two difrences between real gas and ideal gas
Solve Problem: A sample of hydrogen has a volume of 8.56L at 0 deg C and 1.5 atm. Calculate the number of molesof hydrogen present in the sample?
Pressure and Volume
volume decreases
pressure
P1 x V1 = P2 x V2
124L
temperature and volume
goes up as well
True
V1/T1 = V2/T2
8.36L
Temperature and Pressure
increases
Kelvin temperature
P1/T1 = P2/T2
2.58kPa
the combination of Boyle's,Charle's, and Guy- Lussac's gas laws
Kelvin
P1V1/T1=P2V2/T2

PV=nRT
1) real gas molecule has finite size, ideal in just a point with no shape 2)real gas molecules reacts with others, ideal is independent
