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

How much heat (in kcal) must be removed to make ice at –10°C from 2 kg of water at 20°C? (The specific heat of ice is 0.5 cal/g °C.)

2. Relevant equations

Q=cmT

3. The attempt at a solution

I thought this problem was simple,

Q=0.5x2000x30

Then diving by 1000 again to put it into Kcal. 30 is not the right answer.
