Once you have completed the second measurement, increase the volume to the max, 15.0 cm (15.0 nm on screen). Do this by grabbing the handle on the side of the box and pulling it to the left as far as it could go. Your answer will be values for all four gas properties, separated by a comma. Provide the values for the first three properties you set by adjusting the simulation: P, V and T. See Instructions on how to find the values. For the fourth value, n (moles), calculate using the moles using the Ideal Gas Law formula in the directions. Answer will have the same format as other two measurements, Pressure (atm), Volume (L), Temperature (K), Moles.

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.
