Oh my, you question is not about heat capacity but about the latent heat of fusion of water.
to melt one gram of ice at 0 deg C requires 224 Joules or 79.8 Calories
so to melt 10 grams requires 2240 Joules or 798 calories (so pick 800)
specific heat capacity is when there is a temperature change, not a phase change at constant temp like ice to water
then the formula is:
heat in = heat capacity *mass * change in temperature
I need some1 to explain heat capacity to me because the way my lesson is teaching it is EXTREMELY confusing!! A simple explanation would be nice!
Dumb it down 4 a 7th grader!!!!!
If you could use the following question in the explanation, that would be great because this is y i needed an explanation:
How many calories are required to melt a 10g ice cube which is at 0° C?
A) 10 cal
B) 80 cal
C) 800 cal
D) 540 cal
(I was thinking A or B, but im just not sure...)
thnx a bunch!!!

You are welcome, good luck.
