The medicinal thermometer commonly used in homes can be read to ± 0.1 ° F . whereas those in the doctor's office may be accurate to ± 0.1 ° C . Percent error is often expressed as the absolute value of the difference between the true value and the experimental value, divided by the true value: percent error = | truevalue-experimentalvalue | true value ×100% The vertical lines indicate absolute value. In degrees Celsius, express the percent error expected from each of these thermometers in measuring a person's body temperature of 38.9 ° C .

Solution Summary: The author explains that the percent error in a medicinal thermometer, which is used at home and by doctors, is to be calculated.
The medicinal thermometer commonly used in homes can be read to
±
0.1
°
F
. whereas those in the doctor's office may be accurate to
±
0.1
°
C
. Percent error is often expressed as the absolute value of the difference between the true value and the experimental value, divided by the true value:
percent error =
|
truevalue-experimentalvalue
|
true value
×100%
The vertical lines indicate absolute value. In degrees Celsius, express the percent error expected from each of these thermometers in measuring a person's body temperature of
38.9

Suppose you are trying to find the volume of a box based on the given measurements for the length, width, and height of the box, where the height was measured in two parts. length, l = 2.20 in width, w = 3.71 in height, h = 10.4 in + 1 in Calculate the height, ℎ, of the box, first keeping all digits, then rounding to the proper number of significant figures. unrounded h = ____in rounded h =____ in
Calculate the volume (V) of the box using V =l x w x h. Round to the proper number of significant figures.
v=_____in3
At 20 ⁰C, A flask that weighs 368.5 g is filled with 325 mL of carbon tetrachloride. The weight of the flask and carbon tetrachloride is found to be 871.95 g. From this information, calculate the density of carbon tetrachloride and predict if carbon tetrachloride will be denser than water.
Density :
Is carbon tetrachloride denser than water?
