A)Supposing that it remains at that value all the way to absolute zero, calculate the number of calories it would take to change a 0.50g ice cube at absolute zero (-273 degree C}) to 0.50 g of boiling water.B)How does this number of calories compare with the number of calories required to change the same gram of 100 degree C boiling water to 100 degree C steam?
