Coffee 66
What is the final equilibrium temperature?
What is the final equilibrium temperature
when 15 g of milk at 29 C is added to 174 g of
coffee at 66 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.
Q1=Q2
Mc(Tf-Ti) = Mm(Ti-Tf)
(0.174)(Tf - 339) = (0.015)(302-Tf)
Solve for Tf
Tf = 336 degrees Kelvin or 63.06 degrees Celcius
