Could you hardboil and egg on the moon?
Options:
*Yes, because water boils spontaneously on the moon.
*No, because water boils at such a high temperature that it would cause the egg to disintegrate before it became hard-boiled.
*Yes, because the atmospheric pressure keeps the water boiling.
*No, because there is no pressure so the water does not become hot enough to cook an egg.
Water will boil spooontaneously on the moon, flashing to vapor at such a rate it likely would turn to ice and continue to vaporize. The egg might freeze, but it would not cook.
The boiling point of water depends on the outside vapor pressure. At our atmospheric pressure, water boils at 100C, quite warm enough to heat and cook an egg. At an elevation of 29,000 Feet, water boils not at 100C, but at 67C. As one enters space, water "boils" at any temperature.
No, you cannot hardboil an egg on the moon. The first option, "Yes, because water boils spontaneously on the moon," is incorrect. While it is true that water can boil on the moon, it does not boil in the same way as on Earth.
On Earth, water boils at a specific temperature of 100 degrees Celsius (212 degrees Fahrenheit) at sea level, but this boiling point depends on the outside vapor pressure. However, on the moon, there is no substantial atmosphere or significant vapor pressure to maintain the boiling point of water. This means that water will boil at any temperature, even at very low temperatures.
If you were to bring water to the moon's surface, it would flash to vapor rapidly, likely turning into ice and continuing to vaporize. The egg in this scenario might freeze, but it would not cook because there is no sufficient heat to cook it.
Therefore, the correct answer is the fourth option: "No, because there is no pressure so the water does not become hot enough to cook an egg."
