6- A plywood is used as a thermal Insulator in a house. It has a width of 6cm and area of 3m². If the internal temperature is 25C° and the external temperature 50C and the thermal conductivity 0.04 (J/(s.m. Cº), what is the time needed to flow 3 KJ of heat to the house? (2.5/10).
#6. My buddy is starting to get hypothermic (body temperature 306 K) during an epic backcountry ski adventure. Since I'm quite warm (body temperature 310 K), I decide to get in a sleeping bag with him to try and warm him up. What heat transfer mechanism will be most responsible for heating him up? For simplicity, ignore any internal temperature differences across my body (that is, assume my skin temperature is also 310 K). Use num- bers to support your answer (for human skin, you can use the following values: surface area A = 1.50 m², emissivity = 0.970, thickness d= 0.0250 m, thermal conductivty 0.200 ms.K)

A 155 g copper bowl contains 230 g of water, both at 20.0°C. A very hot 300 g copper cylinder is dropped into the water, causing the water to boil, with 4.05 g being converted to steam. The final temperature of the system is 100°C. Neglect energy transfers with the environment. (a) How much energy (in calories) is transferred to the water as heat? 8.6 X kcal (b) How much energy (in calories) is transferred to the bowl? 55 X kcal (c) What is the original temperature of the cylinder? 553.6 X °C Did you use the idea of conservation of energy? That is, did you equate the sum of the energy transfers to zero? For the bowl and cylinder, did you substitute the expression relating an energy transfer, the specific heat, the mass, and the temperature change? For the water, did you use the same expression to get the water to the boiling point? Did you also include an expression for the heat of vaporization? Did you use the given final temperature for each of the three materials?
A 390-g metal container, insulated on the outside, holds 170.0 g of water in thermal equilibrium at 21.0°C. A 18.0-g ice cube, at -15.0°C, is dropped into the water, and when thermal equilibrium is reached the temperature is 12.0°C. Assume there is no heat exchange with the surroundings. The specific heat capacity of water is 4190 J/kg ∙ K, the specific heat capacity of ice is 2090 J/kg ∙ K and the heat of fusion is 3.34 × 105 J/kg. What is the specific heat capacity of the metal of the container?
Because water is a much more efficient thermal conductor than air, marine mammals often have thick layers of blubber (under-skin fat, with a thermal conductivity of 0.250 W/(m °C)) and a small surface-to-volume ratio to minimize the loss of energy by heat to the surrounding water. The beluga whale, Delphinapterus leucas, is a species of whale native to the Arctic and sub-Arctic regions. The core body temperature of this whale is usually 37.0°C, and its basal metabolic rate (BMR) is 7.30 x 104 kJ/day. The beluga often finds itself near the Arctic ice sheet, where the water temperature is very close to 0°C. (a) Modeling the body of the whale as a cylinder of length h = 4.10 m and diameter d = 1.20 m,estimate the average thickness (in cm) of the beluga's blubber required to keep the core temperature of the whale fixed at 37.0°C. (For simplicity, treat the blubber layer on the lateral cylindrical surface as a rectangular slab with a constant area. Take the front and rear surfaces of the…
A child running a temperature of 101°F is given an antipyrin (i.e. a medicine that lowers fever) which causes an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98 °F in 20 minutes, what is the average rate of extra evaporation caused, by the drug. Assume the evaporation mechanism to be the only way by which heat is lost. The mass of the child is 30 kg. The specific heat of human body is approximately the same as that of water, and latent heat of evaporation of water at that temperature is about 580 cal g-1.
Though Babatunde's family take oats for breakfast, her mum decides that today they would take tea. She prepares it and serves Babatunde in an aluminium cup of mass 120 g. Before serving the tea, the cup had a temperature of 20 °C. The 0.30 kg tea that is poured into the cup is at a temperature of 70 °C. Determine the final temperature when thermal equilibrium is attained between the tea and the cup, assuming no exchange of heat with the surounding? (Cen is 4190 J/kg. K, cal = 910 J/kg.K).
Marc attaches a falling 328-kg object with a rope through a pulley to a paddle wheel shaft. He places the system in a well-insulated tank holding 23.2 kg of water.
