- Physics PLEASE HELP -
**drwls**, Saturday, November 10, 2012 at 7:41amFirst you will have to compute the final temperature and determine if all the ice melts. (It does, in this case)

Use the formula they gave you for the entropy lost by the cooling liquid water.

The entropy gained by the melting ice is [80 cal/g]*3000 g/273K

There will be additional entropy gain

ÄS = m c ln(Tf/Ti),

as the melted ice incgeases to the final temperature Tf.

Ti = 273 K m(ice) = 3000 g

Add up all the entropy gains and losses for the final answer.
