Question

a student measured the temperature of boiling water and got an experimental reading of 97.5 what is the percent error?

Answer 1

2.5%

Explanation:

This is the formula for "Percentage Error":

|Approximate Value − Exact Value| × 100%

_____________________________

|Exact Value|

Answer 2

Boiling water = 100 deg C

Experimental reading = 97.5 deg C

Error = 100 - 97.5

= 2.5

Percentage error = 2.5/100 * 100

= 2.5 %
