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.

Arman · Answer

q1=72360J n q2=21672 q=94032J is that right DrBob222

DrBob222 · Answer

No. The 72,360 J is right for the q1 part. I don't know where the 21,573 came from.

DK · Answer

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