A 0.500kg block of metal with an initial temperature of 30 degrees C is dropped into a container holding 1.12kg of water at 20.0 degrees C. If the final temperature of the block-water system is 20.4 degrees C, what is the specific heat of the metal? Assume the container can be ignored, and that no heat is exchanged with the surroundings. (specific heat of water, cw= 4186 J/ kg K
