Question
8. How many calories of heat energy (Q) would be released as a 2,500 g iron (Fe) frying pan at 190˚C cools to 25˚C?
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]
