Hello, I'm Tahmid02016. An edit you recently made to Carnot cycle seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Tahmid02016 (talk) 06:54, 9 March 2021 (UTC)
