Hello, I'm Hhhippo. I wanted to let you know that I undid one or more of your recent contributions to Gas laws because it didn't appear constructive. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! &mdash;&thinsp; H HHIPPO  18:07, 27 November 2012 (UTC)
