The problem involves determining the amount of ice that must melt at 0 degrees Celsius to achieve a mass gain of 6 grams. The context relates to concepts of phase change and energy absorption during melting.
The discussion includes various interpretations of the problem and approaches to finding a solution. Some participants express uncertainty about the equations needed, while others suggest potential methods for calculation. There is no explicit consensus on the correct approach, but several lines of reasoning are being explored.
Participants note the importance of adhering to forum rules regarding the provision of complete answers in homework help threads, indicating a focus on guiding understanding rather than providing direct solutions.
Kurdt said:Hmm I think some use of E=mc2 is needed here. If you can find the energy of 6g then assume that is the energy 'absorbed' by a block of ice to turn it to water.
rdx said:When the ice melts, energy is absorbed. I get an equiv of 6g = 1.3e14 cal and it takes 79.71 cal/g to melt ice. So it seems to require 1.617e6 metric tons, a cube about 117 m on a side.
Kurdt said:Well that's how I'd do it. If you can see any other intention in the question please feel free to contribute.
I must say if you're going to post in other peoples threads in the homework section. Do not post what could be considered full answers as this is against the rules (even if you have doubts over the method).
