Calculate the final temperature of a mixture of 350g of ice cubes at -18 degrees C and 237 g of water at 100 degrees C

Answer 1

add the following heats needed:

ice going to 0 deg: massice*Cice*(18)
melted ice to finaltemp: massice*cwater(Tf-0)

add the heat from the water:
masswater*cwater(Tf-100)

and finally, add all these heats and set it equal to zero, and solve for Tf.

Sum heats gained=0 (remember, if somthing lost heat, it will work our to be a negative heat gained).
