q1 = heat to raise T from -10 to zero.
q1 = mass ice in grams x specific heat solid ice x 10

q2 = heat to melt ice
q2 = mass ice x heat fusion.

Add q1 + q2 = total q.
Answered by Arman
q1=72360J n q2=21672
q=94032J
is that right DrBob222
Answered by DrBob222
No. The 72,360 J is right for the q1 part. I don't know where the 21,573 came from.

For q2 I got 1204.66 (rounded) but now I’m confused a bit
