A pond in winter has a layer of ice 5cm thick. The temperature of the air above the ice is -10C and the temperature of the water directly below the ice is 0C. (i) Find out how much heat passes by conduction through a square meter of ice each second (thermal conductivity of ice = k_ice = 2.2 W/m C) (ii) How would the amount of heat transfer differ if the ice were 7.5 cm thick instead of 5 cm thick?

One half of a kilogram of liquid water at 273 K (0°C) is placed outside on a day when the temperature is 259 K (-14 °C). Assume that the heat is lost from the water only by means of radiation and that the emissivity of the radiating surface is 0.560. Consider two cases: when the surface area of the water is (a) 0.035 m² (as it might be in a cup) and (b) 1.5 m² (as it could be if the water were spilled out to form a thin sheet). For each case, (a) and (b), determine the time it takes the water to freeze into ice at 0 °C. (a) Number (b) Number i Units Units
Compute the energy consumption in units of joules per year, gigawatts (GW), and watts per person as (a) fuel, (b) food, and (c) solar radiation for a country of population density 20 person/km2, an area of 1 million km2, and a fuel energy consumption rate of 250 GJ per person per year. Solar radiation reaching the ground is approximately 150 W/m2. The average person consumes food containing 2000 “calories” per day (1 calorie = 4182 J).

(a)Calculate the rate in watts at which heat transfer through radiation occurs (almost entirely in the infrared) to 4.0 m2 of the Earth's surface at night. Assume the emissivity is 0.95, the temperature of the Earth is 15°C, and that of outer space is 2.7 K. (Include the sign of the heat transfer to 4.0 m2 of the Earth's surface in the value of your answer.) (b)Compare the intensity of this radiation with that absorbed by the Earth from the Sun during the day. The intensity of the radiation from the Sun averages about 800 W/m2, only half of which is absorbed by the Earth. (c)What is the maximum magnetic field strength (in µT) in the outgoing radiation, assuming it is a continuous wave?
