**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](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 the 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** – 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 **Educational Content – Transcription and Analysis****Question on Gas Pressure and Temperature**1. A rigid container filled with a gas is placed in ice (e.g., rigid water bottle filled with gas). The rigidity means the volume remains the same. What will happen to the pressure of the gas? - ○ It will decrease. - ○ It will increase.**Discussion:**According to the principles of gas behavior in a rigid container, when the temperature decreases, the kinetic energy of the gas molecules decreases as well. Consequently, the pressure of the gas will also decrease since pressure is directly proportional to temperature (according to Gay-Lussac's Law), given that the volume remains constant.**Question 13 on Abscess Relieving Methods**An infected tooth forms an abscess (area of infected tissue) that fills with gas as microbes grow. The abscess puts pressure on the nerve of the tooth, causing a toothache. While waiting to see a dentist, the person with the toothache tries to relieve the pain by treating the infected area with moist heat.What property are they trying to reduce to relieve the pain? - ○ Temperature - ○ Volume - ○ Quantity of gas molecules - ○ Pressure**Discussion:**Here, the goal of using moist heat is to reduce the pressure inside the abscess. Increasing the temperature can help the abscess to drain, reducing pressure on the nerve. Thus, the property being targeted is pressure relief.**Question 14 on the Effects of Heating Tissue**An infected tooth forms an abscess (area of infected tissue) that fills with gas as microbes grow. The abscess puts pressure on the nerve of the tooth, causing a toothache. While waiting to see a dentist, the person with the toothache tries to relieve the pain by treating the infected area with moist heat.Will heating the tissue help relieve the pain in the short term? - ○ Yes, it will decrease the gas property and thereby decrease the pain. - ○ No, it will increase the gas property and thereby increase the pain.**Discussion:**Applying moist heat is intended to encourage drainage and reduce pressure, which can initially relieve pain. However, in some cases, heating might exacerbate the condition if not followed by adequate drainage, suggesting the need for careful management.

For ideal gas law, PV= nRT Where the volume of n mols of gas at temperature T and pressure P is =V As the container is rigid, Thus the volume of the container is constant. Thus V is constant. Thus for a fixed amount of gas, pressure is directly proportional to temperature. When a rigid container is filled with gas placed in ice. Thus the temperature of the container decreases. Thus pressure inside the container also decreases. The correct answer is - It will decrease
