A metal piece heated to θ_1,M=1000∘C with a mass of M_M=6.5 kg was cooled in a completely heat-insulated iron container filled with water. The mass of the water in the container is M_W=10 kg and the mass of the container is M_B=2 kg. The initial temperatures of the water and the container were the same and amounted to θ_1,W=10∘C. After complete thermal equilibrium between the immersed metal piece, the water, and the container, a temperature of θ2=80∘C was established.
What is the average specific heat capacity of the metal piece cc in the temperature range between 80∘C and 1000∘C?

Input the result in kJ/(kg*K), round to 3 decimal numbers sperated by a point (example: 0.136).

4 / 10

For a horizontally positioned, non-insulated steam pipe with a length of l=3 m and a diameter of d_a=0.1 the convective heat loss Q_point is to be calculated. The temperature of the surrounding air is θ_f=30∘C and that of the outer wall surface is θ_w=170∘C.

Input the result in kW and round to two decimal numbers seperated by a point without thr unit (example: 145.35)

You would like to drink a cup of very hot coffee with milk early in the morning, but you
are in a hurry and have only 5 minutes until you have to leave for work. At which time
after brewing should you add the cold milk to the coffee and stir in order to decrease the
temperature of the mixture as much as possible:
a) 0 minutes (immediately),
b) 2 minutes, or
c) 4 minutes?
Suppose that the stirring can be done instantaneously and that you need the last one
minute for drinking.

brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature
0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat
capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).

Please enter only the letter of the corresponding answer
