Question

How much heat is absorbed by a 53g iron skillet when its temperature rises from 23oC to 92oC?

Answer 1

We are given with
53 g iron skillet
temperature rise of 23°C to 92°C

We need the specific heat of iron skillet. For iron,
cp = 0.385 J/g°C

To get the heat absorbed, we use the formula
H = m cp ΔT
Subsituting
H = 53g ( 0.385 J/g°C) (92 - 23)
H = 1407.95 J
