Answer :
The percent error in the student's measurement of the boiling point of water is calculated as 2.5%, using the difference between the experimental value and the true boiling point.
The student measured a boiling water temperature of 97.5 C, but the true boiling point of water is 100 C. To calculate the percent error, we use the formula:
Percent Error = (|Experimental Value - True Value| / True Value) imes 100%
Plugging in the values we get:
Percent Error = (|97.5 C - 100 C| / 100 C) imes 100%
= (2.5 C / 100 C) imes 100%
= 2.5%
Therefore, the percent error in the student's measurement is 2.5%.
