Set up a proportion
1 mile/1.6 km = 20,000miles/x
Cross Multiply
x = (20,000) * (1.6)
x = 32,000 kilometers
In order to calculate the amount of energy required, we must first check the latent heat of vaporization of water from literature. The latent heat of vaporization of any substance is the amount of energy required per unit mass to convert that substance from a solid to a liquid. For water this is 2,260 J/g. We now use the formula:
Energy = mass * latent heat
Q = 50 * 2,260
Q = 113,000 J
113,000 Joules of heat energy are required.
In evolution, there are different types of evolution. There is micro evolution and macro evolution. Macro-evolution results in a brand new species. Sometimes, species get separated and evolve in different ways. Sometimes, through macro-evolution 1 of those groups of the same species, become a completely different species. I think that is what is happening here.
