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

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
