The percent error is 6.25%

Step-by-step explanation:

Percent error is given by:

$Percent\ Error=\frac{|Experimental\ Value -\ Accepted\ value|}{Accepted\ value}*100$

Here,

Accepted value = 80.0°C

Experimental Value = 75.0°C

Putting the values in the formula

$Percent\ Error=\frac{|80.0 -75.0}{80.0}*100\\=\frac{|5.0|}{80.0}*100\\=\frac{5.0}{80.0}*100\\=0.0625*100\\=6.25\%$

Hence,

The percent error is 6.25%
