The answer will depend on 400 degrees on which scale. Also, there are likely to be tens (if not hundreds) ofmaterials from the tens of thousands that surround us. Perhaps you could make the question a bit less vague.
The boiling point of astatine is 400 oC.
At 400 degrees Celsius, mercury would be in liquid form. Mercury has a melting point of -38.8 degrees Celsius and a boiling point of 356.7 degrees Celsius.
The boiling point of 30w oil can vary depending on the specific composition of the oil. Generally, the boiling point of motor oils, including 30w oil, can range between 400-600 degrees Fahrenheit.
Boiling point of gasolineThe boiling point of gasoline varies. At atmospheric pressure, it's between 100 and 400 degrees F. A primary cause of this variance is the various additives in the gasoline from different refiners designed to meet different octane requirements.
It is liquid.
27 degrees
The boiling point of natural gas, which is primarily composed of methane, is approximately -162 degrees Celsius or -260 degrees Fahrenheit. This is the temperature at which natural gas changes from a liquid to a gas state.
It is impossible to list the boiling point of crude oil due to the widely varying boiling point of it's numerous compounds, some of which may boil at temperatures too high to be measured. Refined motor oil will boil at around 300 degrees Celsius (572 degrees Fahrenheit).
The average temperature on Mercury is about 400 degrees Kelvin (more than the boiling point of water), but temperatures range from 100 degrees Kelvin (very cold) to around 700 degrees Kelvin (very, very hot).
Paint thinner is mostly acetone. Pure acetone has a boiling point of 56 degrees Celsius at a pressure of 760mm/Hg.
The initial boiling point of furnace oil typically ranges between 250-300°C, while the final boiling point is around 400-450°C. These temperatures indicate the range over which the different components in furnace oil vaporize and are distilled.
Diesel fuels have different chemical compositions, which affect the boiling point. Conventional diesel fuels usually have a boiling range of about 149 degrees C to 371 degrees C.
