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 1

`Q=197505J`

Step-by-step explanation:

From the question we are told that:

Mass
`m=2500g=2.5kg`

Initial heat of pan
`i_h=190 \tetxtdegree`

Final heat of pan
`f_h=25˚C \tetxtdegree`

Generally the equation for Heat energy released is mathematically given by

`Q=mC \triangle T\\\\Q=2.5*462 *(190-26)\\\\Q=1155 *(190-26)\\\\Q=1155 *(171)\\`

`Q=197505J`
