You place 1.0 kg of ice ( at 0 deg c) in a pot and heat t until the ice melts and the water boils off, making steam. How much heat must you apply to achieve this? Also, a printing plate of 20 kg is made of lead. After casting, the solid lead cools to 90 deg c . It is then dropped into a 200 l tank of water initially at 25 deg c. What is the final equilibrium temp? I just don't even know how to start these problems, but I'm sure it's easy. Please help cause I don know what to do!!! Equations: Q=mcT Is what I think you need. Thanks!!!!!
