Question

Your answer is partially correct.
An insulated Thermos contains 120 cm³ of hot coffee at 78.0°C. You put in a 13.0 g ice cube at its melting point to
cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached?
Treat the coffee as though it were pure water and neglect energy exchanges with the environment. The specific
heat of water is 4186 J/kg.K. The latent heat of fusion is 333 kJ/kg. The density of water is 1.00 g/cm³.

In 1986, a gargantuan iceberg broke away from the Ross Ice Shelf in Antarctica. It was approximately a rectangle 160 km long, 40.0 km wide, and 250 m thick. (a) What is the mass of this iceberg, given that the density of ice is 917kg/m3 ? (b) How much heat transfer (in joules) is needed to melt it? (c) How many years would it take sunlight alone to melt ice this thick, if the ice absorbs an average of 100W/m2, 12.00 h per day?
(a) At what temperature does water boil at an altitude of 1500 m (about 5000 ft) on a day when atmospheric pressure is 8.59104N/m2 ? (b) What about at an altitude of 3000 m (about 10,000 ft) when atmospheric pressure is 7.00104N/m2 ?
(a) If a 500mL glass beaker is filled to the brim with ethyl alcohol at a temperature of 500C, how much will overflow when its temperature reaches 210C ? (b) How much less water would overflow under the same conditions?
(a) Calculate the rate of heat conduction through a double-paned window that has a 150-m2 area and is made of two panes of 0.800 cm-thick glass separated by a 1.00 cm air gap. The inside surface temperature is 15.0 C, while that on the outside is 10.0 OC. (Hint: There are identical temperature drops across the two glass panes. First find these and then the temperature drop across the air gap. This problem ignores the increased heat transfer in the air gap due to convection.) (b) Calculate the rate of heat conduction through a 1.60-cm-thick window of the same area and with the same temperatures. Compare your answer with that for part (a).
