How much heat is absorbed by a 66g iron skillet when its temperature rises from 7oC to 20oC?

Respuesta :

01-06-2018

The heat absorbed is calculated using the following equation:
Q = mCΔT

Q = heat absorbed
m = mass = 66 g
C = specific heat of iron = 0.449 J/g.°C
ΔT = temperature change = 20 - 7 =13°C

Therefore,
Q = 66*0.449*13 = 385.242 J
