As seen in the animation, in order to shape a 630.85g piece of steel (SHC = 500 J/kg*OC), you need to heat it up to the point where it is glowing red, which is about 429 OC. Once you have it to the shape you want, you need to cool it down by putting it in a 2.42L tub of water. If the final temperature is 37OC, what is the initial temperature of the water?
