Why is thermal energy produced not generally usable to do work?
1because the thermal energy dissipates too quickly and is not concentrated enough to be used
2because this energy is lost to the universe
3 because thermal energy is a form of energy that cannot be used to do any work
4 because thermal energy does not have the same equivalent to do work as other forms

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
