 Title: Ideal gas law: PV=nRT Post by: ahmedelshfie on April 13, 2010, 07:07:53 pm This applet is explain about (Ideal gas law: PV=nRT) applet created by Prof hwang Modified by AhmedOriginal project:ideal gas law: PV=nRT (http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=632) Title: Re: Ideal gas law: PV=nRT Post by: ahmedelshfie on April 13, 2010, 07:33:49 pm Image general chemistry: http://www.vias.org/genchem/wrapnt_reaction_equilibrium_in_the_gas_phase92.htmlImage from: http://flame.mech.gifu-u.ac.jp/TEST-j/testcenter/Test/problems/images/pistoncylheatinworkout.gifImage from: http://www.ulb.ac.be/sma/testcenter/Test/intro/introimages/cprocesses/pistoncyldoublecv.jpg Title: Re: Ideal gas law: PV=nRT Post by: ahmedelshfie on April 13, 2010, 07:38:45 pm Prof i find  problem in slider (N) when move sliderSimulation stop but i don't know why this happend Please check thankyou Title: Re: Ideal gas law: PV=nRT Post by: Fu-Kwun Hwang on April 13, 2010, 08:46:49 pm It was fine with previous EJS/java version. The problem can be solved if you add the following lines at the top of the initialize pagex=new double[n];y=new double[n];vx=new double[n];vy=new double[n]; Title: Re: Ideal gas law: PV=nRT Post by: ahmedelshfie on April 13, 2010, 08:52:33 pm I do it but is the same problem when i move slider(N) simulation stop And No work need refresh page to work again  ??? Title: Re: Ideal gas law: PV=nRT Post by: Fu-Kwun Hwang on April 13, 2010, 10:24:18 pm Add _pause() to On Press  property and _play() to On Release property of SliderN.Actually, you can find out the run time error from EJS console when you run it.The error message can lead you to find the bug or find way to solve it.
