## Homework Statement

A 3.0kg block of ice made in a fridge has an initial temp. of -5.0[tex]\circ[/tex]C. It

is then moved to a much colder freezer. how much thermal energy is released by the ice as it cools to -40.0[tex]\circ[/tex]C?

## Homework Equations

E

_{H}= mc[tex]\Delta[/tex]T

for water, c = 4186 J/kg/[tex]\circ[/tex]C

## The Attempt at a Solution

E

_{H}= mc[tex]\Delta[/tex]T

E

_{H}= (3.0kg)(4186 J/kg/[tex]\circ[/tex]C)(-40.0[tex]\circ[/tex]C - -5.0[tex]\circ[/tex]C)

= -439530 J

but the answer should be 2.2 x 10^5 J

help?
