Determine the equilibrium temperature when a 5.00 kg block of ice at -10 degrees celsius is added to an insulated container partially filled with 12 kg of water at 13 degrees C.
Homework Answers
Water will lose temp but Ice first goes to zero, then melts and then raises temp again.
Heat lost by water = heat gained by ice
mc dT = (mcdT)ice + mL + (mc dT)water
12 x 4.2 x (13-T) = 5 x 2.1 x (0-(-10)) + 5 x 334 + 5x 4.2 (T-0)
T = -15.
