The essential idea is to calculate the energy of the final mass of water using the heat capacity of water, the volume of the final amount of water and the final temperature of the water.
E = Cp x mass water x Twater = change in energy bucket 1 + change in energy bucket 2
We assume the ...
This solution is provided in 253 words. It uses the heat capacity of water and final volume to find what volume should be taken out.
