Hello, I'm Roxy the dog. I wanted to let you know that one or more of your recent contributions to Mechanical equivalent of heat have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse. Thanks. Roxy the elfin dog . wooF 13:53, 8 June 2020 (UTC)
