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.
STEP 4: Set timer forâ¦. 1  3 minutes for very runny soft-boiled eggs with just-set whites. 2  4 minutes for runny soft-boiled eggs. 3  6 minutes for creamy, custard-y âmediumâ-boiled eggs.  8 minutes for firm (but still creamy) hard-boiled 1  eggs. 10 minutes for firm hard-boiled eggs.  12 minutes for very firm hard-boiled eggs.
