Three words used to describe the individual particles of a gas according to the kinetic-molecular theory. (Hint: A pollen grain display this motion)

What is in continuous random motion?

PV = k or P1V1 = P2V2 states his law.
What is Boyle's Law?
100
An imaginary gas whose particles are infinitely small and which do not interact with each other.
What is an ideal gas?
100
The movement of particles from regions of high concentration to low concentration.
What is diffusion?
200
Gases are highly compressible and have low density because of this.
What is their particles are far apart?
200
The cause of pressure exerted by a gas on its container.
What is collisions with the container walls?
200
V/T = k or V1/T1 = V2/T2 states his law.
What is Charles' Law?
200
The ideal gas assumptions break down under these two conditions.
What are very high pressure and very low temperature?
200

“When measured at the same temperature and pressure, volumes of gaseous reactants and products of chemical reactions are always in simple ratios of whole numbers”

What is Gay-Lussac's Law or the Law of Combing Voumes?

300
This happens when you open the valve between a container of gas and another, empty container.
What is the gas expands to fill both containers?
300
A temperature of 0 Celsius and 1 atm of pressure.
What is standard temperature and pressure?
300
The ideal gas law.
What is PV = nRT?
300
The number of moles of gas if: V = 44.82 L, P - 101.325 kPa, T = 0 degrees Celsius, R = 8.314 L*kPa/mol*K, (round answer to 1 digit)

Of NH3 or SO2, the one you would smell first from across a room and why.

What is NH3 because it is a lighter molecule.

400
A force divided by area.
What is pressure?
400
The temperature of a gas is proportional to this.
What is average kinetic energy?
400
If you have a gas at 300 K and a pressure of 5 atm, what is the pressure if the temperature is raised to 600 K? Assume volume is fixed.
What is 10 atm?
400

Propane, C3H8(g), is a fuel used in many portable barbecues and camp stoves. If a propane tank contains 1.00 kg of propane, this would be its volume at at STP.

What is 508 L?

"Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules."

What is Avogadro's Theory.

500
The standard measure for pressure in science.
What is the Pascal?
500
In kinetic-molecular theory, collisions between gas particles are describes as this.
What is elastic?
500
Sample "A" has twice the pressure of Sample "B". Assuming the temperature and volume of the gases are the same, you conclude this about the number of moles of gas "A".
What is A has 2x the number of moles of B.

The four laws joined by the ideal gas law.
What are Charles', Boyle's, Gay-Lussac's and Avogadro's Laws?

For the following equation, given 9 liters of N2, the volume of NH3 you would have.
3 H2 (g) + N2 (g) --> 2 NH3 (g)

What is 18 liters of NH3?
