A) a 100 gram ice cube is at 10 degrees celcius. how many calories needed to raise it to 0 degrees C.?
B) once its at 0 degrees, how many more calories are needed to melt it?
C) once melted, how many are needed to raise it to 100 degrees C.?
need answers t all!! thank you!!

(A) Multiply the specific heat of ice by the 100 g mass and 10 C (temperature rise).
(B) Multiply the 100 g mass by the heat of fusion. The temperature remains 0 C while ot melts.
(C) Multiply the specific heat of water by 100 g and 100 C.
If you do not know the specific heats of ice and liquid water, nor the heat of fusion, this would be a very good time to look them up. 
does that mean
A= 500 cal/g.
B=8,000
C=10,000
