AZ · Answer

$q = mc \Delta T$

m is mass which they told you is 800 grams
c is the specific heat and the specific heat for water is 4.18 J/g*C
$\Delta T$ is the change in temperature and you're going from 123 degrees Celsius to 0. What is the change in temperature?

q is the heat which you're solving for
