 == Let me add a welcome too == 

 Some of us have been fiddling with the stub you created Heat_capacity_rate, and you may want to take a look. I've crosslinked some see also articles, and you should compare and decide how it might be further matured. It needs a couple more references for starters, and if nothing (out of the top of me head) strikes you as wrong, you can probably remove the stub at this juncture. If you have a question or need a hand with something, feel free to contact me. I'm on the WP:Wc and that link has some other good references too! Best regards //  "
