1) Calculate the amount of energy it takes to melt a wax?Calculate the amount of energy (in Joules) needed to melt a wax? How much energy is this in units of Megatons (see problem 5 on homework 6)?
Problem 5 on homework 6: Calculate the amount of heat energy needed to raise the temperature of Lake Michigan by 1° C. Look up the term "TNT equivalent" and express this in units of megatons (convert
Joules to megatons).
Comment: A typical nuclear warhead in the U.S. nuclear arsenal has an energy yield of about one megaton, and the U.S. currently has about 5,000 warheads in its stockpile, meaning that all the nuclear warheads in the U.S. arsenal can put out ~5000 megatons of energy when detonated. Think about how this compares to
your result
2) the amount of energy a 500 Watt computer takes in an hour.
