An iron block of unknown mass at 185°f is dropped into an insulated tank that contains 0.8 ft3 of water at 70°f. at the same time, a paddle wheel driven by a 100-w motor is activated to stir the water. thermal equilibrium is established after 10 min with a final temperature of 75°f
determine

b)entropy generated during this process

This has nothing to do with school. i wrote a poem to my crush, who i'm asking out soon. tell me if it's cheesy, or cute. "roses are red, violets are blue no love story sounds right if it doesn't include you. dance with me all night, gaze into my eyes i'll hand you my heart, as well as my pride. when i hear your name, my heart goes insane. your all that i want, all that i need promise me you'll stay with me. here it is the final line, jasmine hill will you be mine? " i'm also going to buy her flowers, teddy bear and some food lol. written by me, bre (:
