How much thermal energy is absorbed by 1.00x10^2g of ice at

-20.0°C to become water at 0.0°C?

Two stages to go through.
q1 = heat to move ice from -20 C to 0.0 C
q2 = heat to convert ice @ 0.0 C to liquid H2O @ 0.0 C
===============================
q1 = mass ice x specific heat ice x (Tfinal - Tinitial)
q2 = mass ice x heat fusion ice
Total heat = q1 + q2
Post your work if you get stuck.
Question , why do we have to do heat the liquid after melting the ice if it’s not specified in the question
Like some quesiton it says to make hot chocolate so we know we have to hit the liquid but why are we heating it in this question
Thank you
