At 1 bar, how much energy is required to heat 77.0 g H20(s) at —10.0 •C to H20(g) at 141.0 QC? Use the heat transfer
constants found in this table.
Step 1: How much energy is needed to heat 77.0 g H20(s) from —10.0 •C to 0.0 •C? The specific heat of H20(s) is
c 2.087

Good day. I was wondering if you could look into this question.

Thank you!

Unfortunately, this question has six parts, and I am completely lost as to what and how I am supposed to answer these questions. I know I am supposed to include questions in different threads, but since these are all related, would you suggest having everything in one place as well?
