If you pour 40g of refrigerated milk (at 4 degrees C) into 200g of freshly percolated coffee (at 96 degrees C), what would the final temperature of your coffee be?

Milk has a specific heat capacity of s=3.93J/g degrees C.
Coffee has a specific heat capacity of s=4.18J/g degrees C.
Assume that no heat is lost to the mug or to the surroundings.

Hint.heat lost by coffee=heat gained by milk
