This would work good to explain the verb "boil" in some sort of language learning program I guess. The original source of this image was a water propaganda pamphlet produced by the America EPA youth outreach program (thus clearly public domain) and although the original was black and white, I painstakingly added colour to just make it a little more cliparty.
