Gas Laws Flashcards
What is the formula for pressure?
P = F/A
What is the formula for kinetic energy?
KE = (1/2)m*v^2
What is Diffusion?
The spontaneous mixing of two substances due to their rapid, random motion of particles.
What is Effusion?
It describes the behavior of a fluid as it passes through a small opening
What does temperature measure?
Kinetic energy (motion)
What is STP?
Standard Temperature and Pressure: 0°C & 1atm
What is the formula for Boyle’s law?
P1V1 = P2V2
What is Boyle’s law? (Definition)
As volume goes down, pressure goes up (inverse relationship)
What is the formula for Charles’ law?
V1/T1 = V2/T2
What is Charles’ law? (Definition)
Temp goes down, volume goes down (direct relationship)
What is the formula for Gay-Lussac’s law?
P1/T1 = P2/T2
What is Gay-Lussac’s law? (Definition)
Temp goes up, pressure goes up (direct relationship)
What is the formula for Ideal gas law?
PV = nRT
How do you use standard molar volume?
If at STP, 22.4 Liters per mole can be used to convert
What is Gay-Lussac’s law of combing gas volumes? (Definition)
At constant temp & pressure, the volumes of gases can be expressed as ratios of small, whole numbers
What is Dalton’s law of Partial pressure?
Total pressure of a system is the sum of all the parts
What is the formula for Dalton’s law of Partial pressure?
Pt = P1 + P2 + P3
What are the 5 points of kinetic molecular theory?
1) gas particles are much smaller than the distance between them.
2) gas particles are in constant random motion
3) no kinetic energy lost when gas particles collide
4) all gases have the same avg. kinetic energy at given temp.
5) gas particles do not attract or repel eachother
