(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An ice tray containing 200 g of water at 25 degrees celecius is placed in the freezer. How much heat energy has to be removed to change the water into ice at -4 degrees celcius?

2. Relevant equations

Q= mc(Tf-Ti) + MLf + mc(Tf-Ti)

3. The attempt at a solution

I know that the water is changing into ice however im stumped because I don't know if the water is turning to -4 degrees celcius or 0 degrees celcius?

Any help will be muchly appreciated

Thankyou
