How much heat is needed to melt 50g of ice? Hf =2.10J/g
To the left is a time lapse video showing a glass of ice water while the ice is melting. If the temperature of the ice and water starts at 0 oC, what is the temperature of the ice and water at the end of the video?
Higher than 0 oC
Equal to 0 oC
Lower than 0 oC
Depends on how much ice was added at the start
