Question

Cindy measured and recorded the temperature of a liquid for an experiment. She used a poorly calibrated thermometer and noted the temperature as 100.5 degrees Fahrenheit. The actual temperature of the liquid was 95 degrees Fahrenheit. The percent error in her calculation is:______.

a. -5.79%.
b. 4.08%.
c. 4.08%.
d. 5.79%.

Answer 1

5.79%

Explanation:

The percentage error in the measurement is obtained by;

|measured temperature - actual temperature|/actual temperature ×100

actual temperature= 95°F

measured temperature= 100.5°F

|100.5 - 95|/95×100

%error= 5.79%
