Glacial Movement and Seismicity

We looked up the extra credit answer. We think that It takes 80 calories to melt one gram of ice. We got our answer from http://www.richhoffmanclass.com/chapter4.html

Now our question to you is where are the gummy bears? If you ate them, how many calories would two bears be?

yes, that is correct! it takes about 80 calories (not food calories) or 334 Joules of energy to melt one gram of ice. i am estimating that they have to melt about 50 million grams. how many calories would that be? by the heat that is needed to melt ice is called the latent heat of fusion. a lot of people dont understand that you can have really cold cold ice. well below freezing temps. It takes a long time to heat the ice up to the point where it wants to melt, and then you must add the latent heat of fusion to break the ice bonds and make it water, this extra heat is the latent heat of fusion.Jens and Arla are still here, I would not eat them! are you kidding! they are telling me glacier secrets and are very worried about what the Norwegians are doing with the tunnels here.
