A cube of some frozen substance whose mass is 0.067 kg is taken from a freezer, where its temperature was -13.3 °C, and dropped into a beaker containing the same substance in liquid phase at 1.72 °C. If no heat is gained or lost from outside, how much of the substance (in grams) freezes onto the cube? The latent heat of fusion (AHfus) of this chemical is 32.03 x 104 J/kg and the specific heat capacity is 2,245 J/kg °C. HINT: Find the energy needed to bring the temp of the cube to the temp of the liquid. Then use (AHfus = q / m) to find the mass.
