**[SOLVED] Heat problem**

## Homework Statement

The manager of a fried chicken place wishes to store a ton of poultry at 0 degrees Fahrenheit. Initially the poultry is at 20 degrees Celsius. Calculate the energy in BTUs that is removed in this cooling for storage process.

Assume that the poultry freezes at 32F

Given:

Latent heat: 99 BTU/lb

Specific heats: 0.80 BTU/deg F/lb (above freezing)

0.41 BTU/deg F/lb (below freezing)

## Homework Equations

Was not specifically given any but from the book I'm thinking...

Specific heat

Q = cm[tex]\Delta[/tex]T

Latent heat

L = [tex]\frac{|Q|}{m}[/tex]

## The Attempt at a Solution

Would I even have to use anyone of those equations? I am already given the specific heat and latent heat so those should do me no good right?

[tex]\Delta[/tex]T = 20 - 0 = 20

Q = (.8)(2000)(20)

Q = 32000J

I know I should have to convert all fahrenheit to celcius.

I am really at a loss though what I can use to give me a final BTU. If anyone could give me a push I'd appreciate it. I have no other sources but Internet and the book so other books will not help at this point. Thanks.
