## Homework Statement

How much heat is released when 250 g of water at 10 degrees celcius freezes into ice and cools to -10 degrees celcius?

## Homework Equations

Q=mcΔt

## The Attempt at a Solution

q= (250g)(4186)(283-273)=1.046*10^4 J

than q=(250g)(2090)(263-283)=-1.045*10^4 J

when i subtract the two i get 1*10^4

The answer is -9.86*10^4 what am i doing wrong?
