Chapter 17, Problem 2E(choose chapter or problem)
BIO 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 40o C. 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 7 Co lower than the internal temperature. Express this temperature difference in kelvins and in Fahrenheit degrees. (d) Blood storage. Blood stored at 4.0o C lasts safely for about 3 weeks, whereas blood stored at – 160o C lasts for 5 years. Express both temperatures on the Fahrenheit and Kelvin scales. (e) Heat stroke. If the body’s temperature is above 105o F for a prolonged period, heat stroke can result. Express this temperature on the Celsius and Kelvin scales.
