A physics student drinks her coffee out of an aluminium cup. The empty cup has a mass of 120g
at 20.0°C. Assuming she pours in 300g of coffee at
70°C, what is the final temperature after the coffee
and the cup must have attained thermal
equilibrium? (Assume coffee has the same specific
heat capacity as water and that there is no heat
exchange with the surrounding).​
