Pressure
Pressure Equation
What is Force/Area?
Short Answer.
The number and names of the Gas Laws that we learned(in the honors class).
4 Laws
- What is Gay-Lussac's Law?
- What is Boyle's Law?
- What is Charles' Law?
- What is Combined Gas Law?
The way gases can act more or less ideal.
What are postulates?
Which noble gases have valence electrons less than 8?
Helium is the only noble gas on the periodic table that has been discovered to have valence electrons less than 8 yielding only 2.
T/F
Mrs. Javaras' maiden name was Lentzeras
False.
It was Lentzeres.
Pressure and Volume are proportional
False. They are inversely proportional.
The Boyle's Law equation
What is P1V1 = P2V2?
Short Answer
The theory that describes why gases behave the way they do.
What is the Kinetic Molecular theory?
Xenon is the most reactive noble gas.
While they do exist on the periodic table, all noble gases are inert and are not reactive at all.
What must be consistent in order for equations to work?
Units or measurements?
The units must always be consistent or else equations will not work.
Short Answer.
What is Gas Pressure and how is it caused?
Gas pressure is caused by gas molecules striking objects or the walls of a container.
*from notes.
The Charles Law Equation
What is V1/T1 = V2/T2?
The number of postulates we learned in the honors class.
What are the 5 postulates?
Helium is a noble gas. Why or Why not?
Helium is a noble gas even though it is separated from the other noble gases, they are in the same group and it fills the valence shell principle.
T/F
The first law we learned about was Charles' Law.
False. We learned about Boyle's law first
T/F
The atmospheric pressure per square inch is 14.2lbs per square inch
False!
The answer is 14.7lbs per square inch
The Gay-Lussacs Law Equation
What is P1/T1 = P2/T2?
Short Answer
The optimal conditions for a gas.
What is HIGH temperature and LOW pressure?
T/F
The atomic mass of Krypton and Xenon are 83.798 and 133.24
False!
The atomic mass of Krypton is correct but the atomic mass of Xenon is 131.29
Short Answer.
In Chemistry, we learned that one of the phase changes was from solid to gas. What is the phase change called?
What is Sublimation?
MC
Approximately how many miles thick is the atmosphere?
1. 60
2. 70
3. 80
4. 75
The Earth is surrounded by the atmosphere, a layer of air nearly 80 miles thick

T/F
Boyle's Law explains why racecar drivers have low tire pressure at the start of a race.
False! Gay-Lussac's Law explains why.

3. 4
4. 3
3. 4
Short answer.
Double POINTS
What law(s) apply when a gas sample is in a flexible container, and what law(s) apply when a gas sample is in a rigid container?
Boyle’s law and Charles’s law apply when a gas sample is in a flexible container, which can change volume.
Gay-Lussac’s law applies for gas samples in rigid containers.
