Final answer:
The question involves calculating the amount of ice that melts when placed in warmer water, which requires correct values of specific and latent heat. However, the provided latent heat of ice value seems to be incorrect. Therefore, an accurate answer cannot be given without proper information.
Step-by-step explanation:
The student is asking about the amount of ice that will melt when a certain mass of ice at 0 degrees Celsius is placed in water at a higher temperature. To find the answer, we need to calculate the heat exchange between the ice and the water. The specific heat of water is mentioned as 4200 J/kg°C, and the latent heat of ice is given as 100 J/g.
However, there seems to be an error in the given values or the framing of the question, as the latent heat of fusion of ice is typically much higher (about 334 J/g). Using typical values, we would need to calculate the heat lost by the warm water as it cools down to 0 degrees Celsius and equate that to the heat gained by the ice as it melts. But with the provided values, we cannot proceed with a standard calculation.
Therefore, in this case, the answer cannot be determined without the correct latent heat value, and it is best to inform the student of the possible typo or error and ask for clarification or the correct values.
