Efficiency: You haven't been to the grocery store in a while, and all you can find in your apartment is a few packets of ramen noodles.
a. Calculate how much energy would be needed to raise the two cups of water you need to cook your ramen to its boiling point.
b. List the sources of inefficiency associated with boiling this water in an electric kettle, and find values for or estimate efficiency values for each energy conversion. Trace back as far as your assumed electricity source.
c. How does the situation change if you heat the water on a gas stove? What inefficiencies are avoided, and what are introduced? Estimate (rough estimates are fine, but state your assumptions clearly) the total amount of gas needed to cook your meal
