In a container of negligible mass, 0.200 kg of ice at an initial temperature of -40.0$^\circ$C is mixed with a mass m of water that has an initial temperature of 80.0$^\circ$C. No heat is lost to the surroundings. If the final temperature of the system is 28.0$\circ$C, what is the mass m of the water that was initially at 80.0$^\circ$C?

Two rods, one made of brass and the other made of copper, are joined end to end. The length of the brass section is 0.300 m and the length of the copper section is 0.800 m. Each segment has cross-sectional area 0.00500 m$^2$. The free end of the brass segment is in boiling water and the free end of the copper segment is in an ice–water mixture, in both cases under normal atmospheric pressure. The sides of the rods are insulated so there is no heat loss to the surroundings. (a) What is the temperature of the point where the brass and copper segments are joined? (b) What mass of ice is melted in 5.00 min by the heat conducted by the composite rod?

One end of an insulated metal rod is maintained at 100.0$^\circ$C, and the other end is maintained at 0.00$^\circ$C by an ice-water mixture. The rod is 60.0 cm long and has a cross-sectional area of 1.25 cm$^2$. The heat conducted by the rod melts 8.50 g of ice in 10.0 min. Find the thermal conductivity $k$ of the metal.

An electric kitchen range has a total wall area of 1.40 m$^2$ and is insulated with a layer of fiberglass 4.00 cm thick. The inside surface of the fiberglass has a temperature of 175$^\circ$C, and its outside surface is at 35.0$^\circ$C. The fiberglass has a thermal conductivity of 0.040 W /m $\cdot$ K. (a) What is the heat current through the insulation, assuming it may be treated as a flat slab with an area of 1.40 m$^2$? (b) What electric-power input to the heating element is required to maintain this temperature?
