How many joules of heat must be transferred to a 420-g aluminum pizza pan to raise its temperature from 22°C to 232°C?

Question

How many joules of heat must be transferred to a 420-g aluminum pizza pan to raise its temperature from 22°C to 232°C? The specific heat of aluminum in this temperature range is 0.90 J/g·°C. Show your work. Q = (mass) (Cp) (ΔT)

Q =

Cp =

Mass =

ΔT =

Answer 1

Cp = 0.90 j/g C

Mass = 420 g

ΔT = (232 - 22) C = 210C

Q = 0.90 j/g C x 420 g x 210 C = 79380 j
