Answer:

[tex]Q=197505J[/tex]

Explanation:

From the question we are told that:

Mass [tex]m=2500g=2.5kg[/tex]

Initial heat of pan [tex]i_h=190 \tetxtdegree[/tex]

Final heat of pan [tex]f_h=25˚C \tetxtdegree[/tex]

 

Generally the equation for Heat energy released is mathematically given by

 [tex]Q=mC \triangle T\\\\Q=2.5*462 *(190-26)\\\\Q=1155 *(190-26)\\\\Q=1155 *(171)\\[/tex]

 [tex]Q=197505J[/tex]
