How much heat is absorbed by a 26g iron skillet when its temperature rises from 5oC to 25oC?

The heat capacity for iron is 0.444

Equation

H = m * c * deltat

Givens

m = 26 grams

c = 0.444 J / (g oC)

Δt = 25° - 5° = 20°

Solution

H = 26 grams * 0.444 J/g * C° * 20°

H = 231 = 2.31 * 10^2 technically there should only be 1 sig digit, but I'll give you 3. You can do the rounding.
