A burn produced by live steam at 100oC is more severethan one produced by the same amount of water at 100oC.Verify this, calculate the heat that must be removed from 5.0 g ofwater at 100oC to lower its temperature to34oC.. Then calculate the heat that must beremoved from 5.0g of steam at 100oCto condense it andthen lower its temperature to 34oC, and compare thiswith the answer to part (a).
