Boiling is the process through which water becomes steam, and at sea level, the boiling point of water is 212 degrees Fahrenheit. At different elevations, the boiling point of water could be lower or higher, as determined by the atmospheric pressure in that area.
High pressure constricts the ability of water to boil, so the higher the surrounding pressure, the higher the temperature required to boil water. At higher altitudes, where the pressure is lower, water boils at a lower temperature than it does at sea level. This is the reason for high-altitude cooking instructions found on the packages of many popular grocery items.Learn More
The difference between steam and water vapor is that water vapor is typically the same temperature as the air that is present while steam is above the boiling point of water. The chemical composition of water and steam are identical.Full Answer >
Steam occurs when water goes above 212 degrees Fahrenheit, which is hotter than water when it is at its stable point. While water boils at 212 F, steam is at a much higher temperature as water turns to vapor.Full Answer >
There is not a specific temperature that water must be in order for it to evaporate. However, as temperature rises, evaporation typically increases because water molecules are moving more quickly. The faster they move, the more likely it is that they will break away from the pack and evaporate.Full Answer >
Fresh water freezes at 32 degrees Fahrenheit, which is 0 degrees Celsius and 273.15 degrees on the Kelvin scale. Seawater freezes at a slightly lower temperature than fresh water due to its high salt content.Full Answer >
