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.
Have you ever experienced having a fever? You usually touch your forehead or
neck to check if you have a fever or not. You use your sense of touch to tell whether
an object is hot or cold or one is hotter or colder than the other. When bathing a
baby, you dip your fingers in the water, and when you prepare baby's milk, you
sprinkle a few drops of milk on your wrist to check if the temperature is just right.
When you are about to fry some food, you sprinkle some water to see if the frying
pan is already hot. When you feel you are warm, you often say you have a high
temperature. When an object is cold, you often say it has a low temperature.
Temperature is commonly associated with coldness or hotness of a body. How
do we quantify this difference in the hotness or coldness of a body? You might have
experienced that your mother checked your temperature by putting a small glass
tube, called a thermometer, in your underarm.
