- Temperatures in Biomedicine. (a) Normal body temperature. The average normal body temperature measured in the mouth is 310 K. What would Celsius and Fahrenheit thermometers read for this temperature? (b) Elevated body temperature. During very vigorous exercise, the body’s temperature can go as high as 40OC. What would Kelvin and Fahrenheit thermometers read for this temperature? (c) Temperature difference in the body. The surface temperature of the body is normally about 7CO lower than the internal temperature. Express this temperature difference in kelvins and in Fahrenheit degrees. (d) Blood storage. Blood stored at 4.0OC lasts safely for about 3 weeks, whereas blood stored at -160OC lasts for 5 years. Express both temperatures on the Fahrenheit and Kelvin scales. (e) Heat stroke. If the body’s temperature is above 105OF for a prolonged period, heat stroke can result. Express this temperature on the Celsius and Kelvin scales.Question 26 Suppose the sun was twice its current temperature. Recall, the sun is 7 x 105 km in radius, with a surface temperature of 5800 K., and our distance from the sun is D = 150 million km. Using the equation to model the temperature of the earth, (sun)1/4 Tsun and remembering you have to work in the absolute temperature 4D² scale (OK = -273°C), what would happen to the temperature of the earth (in Kelvin scale)? It would be a quarter times as hot. It would twice as hot. It would be four times as hot. It would be half as hot.Typical temperatures in the interior of the Earth and Sun are about 4000°C and 15 x 106°C, respectively. Determine the equivalent of these temperatures in Kelvin.

Problem: The averaged surface temperature of the Pacific Ocean in summer is 20.0 oC and 4.00 oC at 10.0 m depth. What is the thermal power conduction through the ocean per 1 meter squared area (1 m2)? (thermal conductivity of water=0.61 W/m∙K)What would be the temperature of 40.0 g of 22°C water mixed with 60.0 g of 80°C water? Answer in degrees Celsius. Here's the logical pathway to find the answer: The cold water absorbs heat according to Q1 = 40*4.186*(T-22). The hot water loses heat according to Q2 = 60*4.186*(80-T). Q1 must equal Q2, so solve for T, the equilibrium temperature.
