Question

How much heat is absorbed by a 72g iron skillet when its temperature rises from 6oC to 27oC?

Answer 1

we will be using formula of heat absorbed

`Q=mc \Delta T`

where

Q is heat absorbed

m is mass

c is specific heat of iron skillet

`\Delta T` is temperature change

we are given

`m=72g`

`c=0.449J/g`

`\Delta T=27-6`

`\Delta T=21`

now, we can plug values

`Q=72*0.449*21`

`Q=678.888J`

so,

heat absorbed is 678.888J............Answer
