How many joules of heat must be transferred to a 410-g aluminum pizza pan to raise its temperature from 32oC to 232oC? The specific heat of aluminum in this temperature range is 0.96 J/g x oC.

recall that heat absorbed released is given by

Q = mc*(T2 - T1)

where

m = mass (in g)

c = specific heat capacity (in J/g-k)

T = temperature (in C or K)

*note: Q is (+) when heat is absorbed and (-) when heat is released.

substituting,

Q = (480)*(0.97)*(234 - 22)

Q = 98707 J = 98.7 kJ

Explanation:

A=48 CM2

Explanation:

A=9 X 10

A=90 CM2      9-2=7

A=6 X 7

A=42 CM2

A=90-42

A=48CM2
