What is the boiling of water in celisius an Fahrenheit?
At normal altitudes, pure water boils at 212 degrees Fahrenheit, 100 degrees Celsius.
What are the boiling points of water in Fahrenheit and Celsius?
At sea level pressure, on the Fahrenheit scale, water boils at 212 °F. On the Celsius scale, water boils at 100 °C (the "degrees", or intervals, are larger in Celsius than in Fahrenheit). At higher altitudes (lower air pressure), water boils at a lower temperature. Near the top of Mount Everest, the boiling temperature is only about 160°F or 72°C. (see related question)
Why does water boils at lower temperatures than in a valley?
Water boils at lower temperatures at higher altitudes because the atmospheric pressure is lower. In a valley, the air pressure is greater, which allows water to reach a higher temperature before boiling. At higher altitudes, where the air pressure is lower, the boiling point of water decreases.
Why would water in a laboratory boil at a temperature lower than 100 degrees celsius?
Not only in the laboratory, also at higher altitudes. The boiling point of water depends on the pressure. "100 degrees" is only at some pressure defined as standard pressure. At high altitudes (cities like La Paz, for example), it takes longer to cook food - because water boils at a lower temperature.Not only in the laboratory, also at higher altitudes.

Why a fresh cup of tea made with boiling water is not as hot at higher altitudes as it is at sea level?
Because, water boils at lower temperatures at higher altitudes, because there is less air pressure pushing down on the liquid to prevent it from boiling and be released into the air.
The fixed points of water in celsius?
Water freezes at 0 degrees and boils at 100 degrees Celsius
What reference points do you use in calibrating the scale of a thermometer?
The point at which water freezes and the point at which water boils.
How would the boiling point of a liquid change by measuring it in Denver altitude-5000ft?
Water normally boils at 100 °C. High elevation cooking generally takes longer. In Denver, water boils at approximately 95 °C. Boiling point of a liquid lowered in Denver.
Why do hard boiled eggs take longer to cook in different parts of the world?
Because altitude (how far above sea level you are) partly determines cooking time. Different parts of the world have a wide range of altitudes. At sea level, water boils at 100 degrees Celsius. At higher altitudes (lower pressures) it boils at a lower temperature.
What is the difference in boiling points for iron and water?
Water boils at 212°F. Iron's boiling point is 5,182°F. Quite a difference.
When is steam produced?
Steam is produced whenever water boils, which occurs at 100 degrees Celsius at standard pressure and temperature (boiling point changes at altitudes because of the pressure change, remember).
Is there a relationship between boiling and pressure?
Yes, there is. Higher pressure increases the boiling point and lower pressure decreases it. That is why a pressure cooker works and why water boils at lower temperatures in high altitudes.
