- Q2. Calculate the rate of heat conduction out of the human body, assuming that the core internal temperature is 37.0C , the skin temperature is 34.0C , the thickness of the tissues is about 2cm, and the surface area is 2 m^2. How much heat is lost in one hour?[thermal conductivity of human skin = 0.2 J/(s m C) ]3. In an experiment to determine the thermal conductivity of a bar of a new alloy, one end is maintained at 0C and the other at 100C. The bar has a cross-sectional area of 1cm? and a length of 20cm. If the rate of heat conduction through the bar is 34 Watts, what is the thermal conductivity of the bar? उ 券2. You are sick, and your temperature is 312.0 kelvins. Convert this temperature to the Fahrenheit scale.
- 092. A bowl of water has a temperature of 50°C. It is put into a refrigerator where the temperature is 5°C. After 0.5 hours, the water is stirred and its temperature is measured to be 20°C. It is then left to cool further, take t in Newton's law of cooling to be measured in minutes. Use Newton's law of cooling to predict when the temperature will be 50°C.2. A thermometer is removed from a room where the temperature is 70°F and is taken outside, where the air temperature is 10°F. After half a minute the thermometer reads 50°F. What is the reading of the thermometer at t = 1 minute? How long will it take for the thermometer to reach 15°F?
