One end of an iron poker is placed in a fire where the temperature is 440 °C, and the other end is kept at a temperature of 26.4 °C. The poker is 0.761 m long and has a radius of 3.84 x 103 m. Ignoring the heat lost along the length of the poker, find the amount of heat conducted from one end of the poker to the other in 6.00 s. Take the thermal conductivity of iron to be 79 J/(s m Cº).

During heavy exercise, the body pumps 2.00 L of blood per minute to the surface, where it is cooled by 2.00C. What is the rate of heat transfer from this forced convection alone, assuming blood has the same specific heat as water and its density is 1050kg/m3 ?
At 25.0 m below the surface of the sea, where the temperature is 5.00C, a diver exhales an air bubble having a volume of 1.00 cm3. If the surface temperature of the sea is 20.0C, what is the volume of the bubble just before it breaks the surface?
A Styrofoam box has a surface area of 0.80 m and a wall thickness of 2.0 cm. The temperature of the inner surface is 5.0C, and the outside temperature is 25C. If it takes 8.0 h for 5.0 kg of ice to melt in the container, determine the thermal conductivity of the Styrofoam.
Two cylindrical metal rods—one copper, the other lead—areconnected in parallel with a temperature of 21.0 °C at one end and112 °C at the other end. Both rods are 0.650 m in length, and the leadrod is 2.76 cm in diameter. If the combined rate of heat flow throughthe two rods is 33.2 J>s, what is the diameter of the copper rod?
Consider a 20 cm thick granite wall with a thermal conductivity of 2.79 W/m·K. The temperature of the left surface is held constant at 50°C, whereas the right face is exposed to a flow of 22°C air with a convection heat transfer coefficient of 15 W/m2·K. Neglecting heat transfer by radiation, find the right wall surface temperature and the heat flux through the wall.
A copper bar of thermal conductivity 401 W/(m·K) has one end at 114°C and the other end at 24.0°C. The length of the bar is 0.180 m, and the cross-sectional area is 1.00 × 10−6 m2. If two such bars were placed in parallel (side by side) with the ends in the same temperature baths, what would the rate of heat conduction P be?
A brass bar is joined at one end to a 70 cm copper bar and at the other end with boiling water at 1 atm. In order to achieve conductive heat transfer, the copper-free end is brought into contact with a mixture of water and ice also at 1 atm. Both bars have a cross sectional area of 0.00500 m2. The sides of the rods are insulated, so there is no heat loss to the surroundings. If after 5 minutes 50 g of ice melts, find the length of the brass bar.
Suppose you place 0.245 kg of 20.5°C water in a 0.45 kg aluminum pan with a temperature of 143°C, and 0.0085 kg of the water evaporates immediately, leaving the remainder to come to a common temperature with the pan. What would be the final temperature, in degrees Celsius, of the pan and water? The heat of vaporization of water is Lv = 2256 kJ/kg. You may neglect the effects of the surroundings and the heat required to raise the temperature of the vaporized water. Te =

One end of a 0.33-m copper [k = 390 J/(s·m·C°)] rod with a cross-sectional area of 1.0 × 10-4 m2 is driven into the center of a sphere of ice at 0°C (radius = 0.14 m). The rod is horizontal and its other end is fastened to a wall in a room. The rod and the room are kept at a constant temperature of 21°C. The emissivity of the ice is 0.93. What is the ratio of the heat per second gained by the sphere through conduction to the net heat per second gained by the ice due to radiation? Neglect any heat gained through the sides of the rod.
