Temperature change of ice water

[kmarlow123]

A tub of icy water at 0 degrees C hold 100 gallons. You put a 25 pound watermelon with a temperature of 29.4 degrees C. The tub is wrapped in blankets to avoid heat loss. What will be the final temperature of the watermelon, considering that a watermelon is mostly water?

Would you like to make some sort of attempt at the answer?

I am attempting to help my nephew with the problem but I can't remember how to go about setting up a problem like this, I don't need the answer, just some help on setting it up.

Sorry - there is a homework forum which puts up a template to fill in what you have done so far. There is no point in us just supplying answers to homework questions

There is an equation linking the amount of energy to the temperature change
Q = mcT, where c is the specific heat capacity of water

The energy lost by the watermelon = the energy gained by the water.
