SUMMARY

The discussion focuses on calculating the heat required to melt ice at -12°C with a mass of 0.55593125 kg. The correct formula to use is Q = mcΔT for the initial heating of ice, followed by the addition of the latent heat of fusion for the phase change. The latent heat of fusion for ice is essential in determining the total heat required. The participant initially misapplied the equations but corrected their approach after realizing the importance of including the latent heat of fusion.

Homework Statement


If ice is at(-12) deg c and has a mass of .55593125kg, how much heat is required to melt the ice.


Homework Equations


Q=mcT



The Attempt at a Solution


i tried Q=mc(water)T and Q=mc(ice)T but both were marked wrong. can you show me what I am doing wrong here?

Show the actual numbers you're using.

You did remember the latent heat of fusion, didn't you?
 
ohhh yes. i forgot the latent heat of fusion. i got the correct answer now. thank you for your assistance.
