Question
Description You will use an online simulation to manipulate and calculate the four properties of gases: Pressure, Volume, Quantity, and Temperature. You will also apply your knowledge to several scenarios.
To begin, open the simulation, Gases Intro, from https://phet.colorado.edu/sims/html/gases-intro/latest/gases-intro en.html. This will open it in another window. Select the simulation box Intro at the bottom. When
it opens, check Width to show the width of the box. You should leave the rest unchecked. We will only use Heavy Particles. Play around with the simulation to see how to adjust the volume/width (handle on left of
box), temperature (bucket below with either ice or fire), and quantity (using the pump handle to right of the box). Keep the box sealed by keeping top door closed. When you are ready to do the experiments,
reset the simulation by pressing the white eraser button on bottom right, make sure width is 10.0 nm, and set to heavy particles (purple gas molecules).
Instructions To do first experiment, pump the gas pump to put gas into the chamber. Only use between 3 and 7 pumps. Increase the temperature to a number you like between 100 K and 500 K, using the fire/ice bucket on
bottom. Do not change the chamber width for now, keep it at 10.0 nm (handle on left of chamber). Do not open the chamber to let gas molecules out (handle on top of chamber).
Calculating moles using the Ideal Gas Law: PV nRT, where R = 0.0821
Once you have everything how you like it, you will calculate how many moles of gas are in the chamber, by using the Ideal Gas Law. Recall the Ideal Gas Law requires specific units: atm, L, moles, and Kelvin.
Pressure
Is indicated by the circular instrument on the top right of the chamber. It is conveniently already in atmospheres.
Volume - Determine the volume in nm^3 by multiplying the width, height, and depth of the chamber. Depth is always 1.00 nm and height is always 10.0 nm. Width is adjusted by you to 10.0 nm or 15.0 nm,
depending on the experiment. Volume then is: width you adjust X 10.0 nm X 1.00 nm. Simplifying, it is the width you select X 10.0, with units of nm^3. To simplify calculations assume your volume answer in nm^3 are
actually Liters (L), when calculating the Ideal Gas Law.
Temperature- This is indicated by the thermometer, conveniently already in units Kelvin.
Quantity- for these experiments you will be calculating the quantity, or moles, of gas under each scenario. What is the solution when you solve the Ideal Gas Law, PV=nRT, for n, moles? R = 0.0821.
