What is the final equilibrium temperature
when 7 g of milk at 5C is added to 117 g
of coffee at 68C? Assume the specific heats
of milk and coffee are the same as that of
water, and neglect the specific heat of the
container.

The sum of the heats gained is zero.
Heatgainedmilk+heatgainedwater=0
7*c*(Tf-5)+117c*(Tf-68)=0
solve for Tf
Heatgainedmilk+heatgainedwater=0
7*c*(Tf-5)+117c*(Tf-68)=0
solve for Tf
