Consider a person standing in a room at 20°C with an exposed surface area of 1.7 m2. The deep body
temperature of the human body is 37°C, and the thermal conductivity of the human tissue near the skin is
about 0.3 W/m K. The body is losing heat at a rate of 150 W by natural convection and radiation to the
surroundings. Taking the body temperature 0,5 cm beneath the skin to be 37°C, determine the skin
temperature of the person.

You are given 204 g of coffee (same specific heat as water) at 80.0°C (too hot to drink). In order to cool this to 60.0°C, how much ice (at 0.0°C) must be added? Ignore the heat capacity of the cup and heat exchanges with the surroundings. Specific heat capacity (15.0°C) of water is 4.186 kJ/(kg-K). The latent heat of fusion of water is 333.7 × 103 J/kg.
The average thermal conductivity of the walls (including windows) and roof of a house in the figure shown below is 4.8 x 104 kW/m - °C, and their average thickness is 20.8 cm.

What is the rate of heat transfer in J/s through the body's skin and the fat layer just beneath its surface? Treat the skin and fat as a single layer that is 1.20 cm thick. Assume the temperature of the inner surface of the layer corresponds to internal body temperature, or 36.7 °C, and the temperature of the outer surface of the layer corresponds to skin temperature, or 34.0 °C. Take the total surface area of the layer to be 1.50 m² and use a value of 0.413 W/(m-C°) for the average thermal conductivity of the layer. Number Units
