For the purposes of this simulation, a pure-metal planet has a density of 8 grams per cubic centimeter (the density of iron) and a pure-rock planet has a density of 3 grams per cubic centimeter (an average value for silicate rock). Questions to Consider:
Depending on how cooked you like your hard boiled eggs, the eggs should be done perfectly in 10-12 minutes. That said, depending on your altitude, the shape of the pan, the size of the eggs, the ratio of water to eggs, it can take a few minutes more.. Turn off the heat, keep the pan on the hot burner, cover, and let sit for 10-12 minutes. If you have the type of stove burner that doesn't retain any heat when turned off, you might want to lower the temp to low, simmer for a minute, and then turn it off.
When you boil an egg, a physical change occurs that causes it to harden. The time it takes to hard boil an egg depends on the size of the egg. Give the egg time to reach room temperature, about 12 to 15 minutes. Place the eggs in a pan of water and give the water time to boil. It should take eight to 10 minutes for the water to begin to boil, less time if you cover the pan with a lid. You can also add salt to the water to encourage the water to boil faster.
