(c) Temperature difference in the body. The surface temperature of the body is normally about 7c° lower than
the internal temperature. Express this temperature difference in kelvins and in Fahrenheit degrees.
(d) Blood storage. Blood stored at 4.0°C lasts safely for about 3 weeks, whereas blood stored at -160°C lasts
for 5 years. Express both temperatures on the Fahrenheit and Kelvin scales.

A person taking a reading of the temperature in a freezer in Celsius makes two mistakes: first omitting
the negative sign and then thinking the temperature is Fahrenheit. That is, the person reads -x°C as
X°F. Oddly enough, the result is the correct Fahrenheit temperature. What is the original Celsius reading?
Round your answer to three significant figures.
°C
What is a temperature of 62.0°F on the Celsius and Kelvin scale?
a)The temperature on the Celsius scale is oC.
b) The temperature on the Kelvin scale is K
