The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature:A substance is solid if both the melting and boiling points are above room temperature.A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature.A substance is a gas if both the melting point and boiling point are below room temperature.
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).
Boiling something,for example water,is when the liquid HAS to be above 100 degrees Celsius. Heating something is just making it WARMER
boiling point
Because the pressure is higher.
Ionic compounds have boiling points of
If the melting point is at 1240 degrees C then it is most likely an ionic compound, because ionic compounds have their melting points above 800 degrees C while the molecular compounds have their melting point at or below room temperature.
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
as the evaporation occurs under the atmospheric pressure that is492degr and the boiling point occurs above the atmospheric pressure different liquids have different boiling points just the boiling point of water is 100deg c

-- pure alcohol at room temperature -- mercury at room temperature -- oxygen below its boiling temperature -- iron above its melting temperature -- nitrogen below its boiling temperature -- salt above its melting temperature -- gold above its melting temperature -- any other element or compound that is not H2O, above its melting temperature and below its boiling temperature
This method is used whenever there is enough of the compound to perform a distillation. The distillation method of boiling point determination measures the temperature of the vapors above the liquid. Since these vapors are in equilibrium with the boiling liquid, they are the same temperature as the boiling liquid.
The boiling point of water is not 100 ºC. The boiling point of water is 100 ºC at 1 atmosphere pressure. If you boil water, the temperature can range from 93 to 101 ºC depending on atmospheric pressure of the day and how elevated above sea level you are.
If they petrol you're referring to includes things such as the butane in lighters and the propane used in some grills, the gas is liquefied under pressure. As pressure increases, so do the boiling points of most substances. Under normal pressure, propane and butane have boiling points below room temperature and are therefore normally gasses. At higher pressure the boiling points are above room temperature and so they are liquids.
it is above

Heat it past its boiling point.
