What is the final equilibrium temperature

when 7 g of milk at 5�C is added to 117 g
of coffee at 68�C? Assume the specific heats
of milk and coffee are the same as that of
water, and neglect the specific heat of the
container.
Answer in units of �C

1 answer

The sum of the heats gained is zero.

Heatgainedmilk+heatgainedwater=0

7*c*(Tf-5)+117c*(Tf-68)=0

solve for Tf
