# Joint Entrance Examination/2000 Screening/Q007 Monoatomic Ideal Gas and a frictionless piston

* Welcome to the Highschool Help Forum!
* The forum is currently in "Beta" stage of development. You can ask questions and answer/discuss them. The basic functionalities are present. What's required is a more aesthetic look to the Static pages and a more user friendly setup. This will happen over the time gradually as we start creating some content.
* The site has a lot of tools, like posting mathematical calculations, images and diagrams; categorizing questions and so on. Having them here is NO GOOD unless you know how to use them. I am thoroughly against compiling a list of these features and then writing about them. As soon as you do not understand how to do something or use a certain feature, report that on "How To"s Section of the forum. Your queries will be answered there.
* If you have any ideas/discussion regarding the site/comments, please go to Discussions regarding Highschool Help Forum
* Lastly, thanks for joining in the site's development process! It matters!

| Original Question by Dharav Here's the question... A monoatomic ideal gas, initially at temperature T$_1$ , is enclosed in a cylinder fitted with a frictionless piston. The gas is allowed to expand adiabatically to a temperature T$_2$ by releasing the piston suddenly. If L$_1$ and L$_2$ are the lengths of the gas column before and after expansion respectively, then T$_1$/T$_2$ is given by (L$_1$/L$_2$)^(2/3) (L$_1$/L$_2$) (L$_2$/L$_1$) (L$_2$/L$_1$)^(2/3) Posted by Dharav 13:49, 17 August 2009 (UTC) | What's Up?
