a) Temperature difference in the body. The surface temperature of the body is no

Question

a) Temperature difference in the body. The surface temperature of the body is normally about 7.00 C lower than the internal temperature. Express this temperature difference in kelvins and in Fahrenheit degrees.

TK,TF = K,F

b) Blood storage. Blood stored at 4.00 C lasts safely for about 3.00 weeks, whereas blood stored at -160 C lasts for 5 years. Express -160 C on the Fahrenheit and Kelvin scales.

TF,TK = F,K

c) Heatstroke. If the body's temperature is above 108 F for a prolonged period, heat stroke can result. Express this temperature on the Celsius and Kelvin scales.

TC,TK = C,K

Explanation / Answer

Here ,

a) Temperature difference in degree C = 7 C

as temperature differnece in K = Temperature difference in degree C

temperature differnece in K = 7 K

-------------------

temperature differnece in degree F = TC * 1.8

temperature differnece in degree F = 7 * 1.8

temperature differnece in degree F = 12.6 degree F

b)

in Kelvin

T = -160 + 273 K

T = 113 K

temperture in kelvin is 113 K

as TF = TC * 1.8 + 32

TF = -160 * 1.8 + 32

TF = -256 degree F

c)

for TF = 108 degree F

108 = TC * 1.8 + 32

TC = 42.22 degree C

temperature is 42.22 degree C

TK = 42.22 + 273

TK = 315.22 K

temperature in K is 315.22 K
