Two - 20.0 g ice cubes @ -20 degrees C are placedinto275 g of water @ 25 degrees C. Assuming no energy is transfered to or from the surroundings caculate the final temperature of the water after the ice melts.

Answer 1

[mass ice cubes x specific heat ice x (Tfinal-Tinitial)] + [mass ice cubes x heat fusion H2O)] + [mass melted ice cubes x specific heat H2O x (Tfinal-Tinitial)] + [mass water x specific heat H2O x (Tfinal-Tinitial)] = 0
Substitute and solve for Tfinal.
