Gas Properties - Simulation

By -

 

Topics

  • Ideal Gas Law
  • Kinetic Molecular Theory
  • Diffusion
  • PV Work
  • Maxwell-Boltzmann Distribution

Description

Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. Examine kinetic energy and speed histograms for light and heavy particles. Explore diffusion and determine how concentration, temperature, mass, and radius affect the rate of diffusion.

Sample Learning Goals

  • Determine how changing a variable among P, V, N, and T influences other gas properties.
  • Describe the relationship between particle-wall collisions and pressure.
  • Predict how changing temperature will affect the speed of molecules.
  • Predict the speed of molecules in thermal equilibrium based on the relative masses of molecules.
  • Identify when pressure-volume work is done on or by a gas.
  • Explain how two gases mix.
  • Design an experiment to find the factors which affect the rate of diffusion.

Most countries were forced to put in place strict regulations that will help control the pace at which the virus spreads. In South Africa there was a national level 5 lockdown that was implemented in early March. This required citizens around the country to remain in their homes, unless if they needed to do essential grocery shopping or go to the clinic or pharma

How did we get approved for adsense?

 What did we do to get approved? We all know how hard it is to get approved by Google Adsense, so I will explain what we had to do to be approved in this post. Before we start it's worth mentioning that we got rejected many times before we finally got accepted. Content content on the website should be original, that's the most important thing. It doesn't matter what you are writing about but it's important to have original content, meaning you write what you think without copying and pasting or copying someone word to word without adding any value to it or any original thoughts. Website domain This is my opinion, I think when you apply for AdSense you should use a domain that is top level like (yourblog.com / yourblog.net/ yourblog.org) because this makes you look authentic and that you will not be scamming or spamming from a domain that ends with .ml, .gk, .tc, etc.  structure your website should not rely on the browser for navigation, every page should have a way to n

A lovely restaurant experience.

The Grass Here I was walking, minding my own business, then a restaurant so immaculate on the outside caught my attention. It had the view of the dam, flying ducks, birds chirping the works, so I thought to myself, let me try this place out. Of course for copyright and legal purposes I will give this place a false name, I will call it "The Grass". Upon entering you meet this wonderful calm, peaceful atmosphere, with almost the entire restaurant staring at you as if you a celebrity (No really they were staring)I do not know if there was something off with my makeup or my boyfriends ridiculous cowboy hat that he was wearing. Anyways, upon entering things were going so smoothly up until the moment of picking a table and decide what we should eat came about and ruined all that. Nothing but confusion First of all, the menu was piece of white A4 paper, typed in romans font size 14 (so much for creativity). There was no prices on the menu, they tried to be clever and use catchy term

 ISINGENISO  Umyalezo yilokho umbhali asixwayisa noma aseluleka ngakho enovelini/yisifundo esitholakala uma sifunda inoveli. Umyalezo uchaza ukuthi umbhali ubehlose ukusazisani ngokubhala le ndaba. Umyalezo wale noveli uthi: Ukungabi nesimilo esihle kungaba nemiphumela engemihle empilweni yethu neyabanye abantu. UMZIMBA  UDumazile  Ukungabi nesimilo esihle kukaDumazile esemncane noma eseganile kwadala le miphumela engemihle elandelayo:  • Ukuqoma uthisha uMoloi ebe eyingane yesikole okwaba nomphumela wokukhulelwa ingane kaMoloi nokuxabana noMisi Hlophe bebanga uMoloi  • Ukuxoshwa kukaDumazile esikoleni kunomphumela omubi ngoba kugcina kuxabanise abazali bakhe.  • Ukuqoma uSithole ngemuva kokuxoshwa nguMaNzimande emzini kaSithole kwagcina kunomphumela wokukhulelwa ingane kaSithole.  • Ukuhlela isu lokushisa isitolo sikaSithole kwaba nomphumela wokuthi uSithole agcine esehlupheka ngoba umshwalense wala ukusikhokhela.  • Ukuba nobudlelwano bezocansi noMthovovo, nokubuyelana noMoloi noSith
