a student mixes 88.6g of water at 74.3 degree Celsius with 57.9g of water at 24.8 degree Celsius in an insulated flask.What is the final temperature of the combined water.
Answered by DrBob222
heat lost by warm water + heat gained by cool water = 0

[mass warm water x specific heat water x (Tfinal-Tinitial)] + [mass cool water x specific heat water x T(final-Tinitial)] = 0
Solve for Tfinal.
