What do boiling point and melting point have to do with the phase of matter of an element at room temperature?
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.
What state would melting and boiling point be st 1000 degrees celsius?
At 1000 degrees Celsius, most substances would be in a liquid state, as this is above the boiling point for many materials. However, some substances with higher boiling points, like tungsten or carbon, may still be in solid form even at 1000 degrees Celsius.
What is the difference between boiling points and heating curves?
Boiling something,for example water,is when the liquid HAS to be above 100 degrees Celsius. Heating something is just making it WARMER
What is the boiling point of motor oil?
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).
Does rock salt have a boiling point?
Yes, rock salt does have a boiling point. When heated sufficiently, rock salt will undergo a phase change from a solid to a liquid state. This typically occurs at temperatures above 1474 degrees Fahrenheit (801 degrees Celsius).
How do you determine the type of compound ionic or molecular from the melting point such as 1240 degrees C?
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.
How can you use boiling points and melting points to determine a solid liquid or gas that an element would be in at a certain 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.
Ionic compounds have boiling points that are often above?
Ionic compounds have high boiling points due to the strong electrostatic forces of attraction between the positively and negatively charged ions. These forces must be overcome to break apart the structure, requiring a significant amount of energy.
How is evaporation different from boiling?
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
What do boiling point and melting point have to do with the phase of matter of an element at room temperature?
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.
What are 5 liquids that do not have water?
-- 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
how can the boiling point of the distillate be used to identify a substance?
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.
What is false about boiling points?
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.
How does petrol gas gets liquefied?
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.
A liter of gasoline will boil at?
Gasoline is a complex mixture of hydrocarbons with different boiling points. Some components of gasoline will boil at temperatures below 100 degrees Celsius, while others have boiling points above 200 degrees Celsius. So, a liter of gasoline will have a range of boiling points depending on its composition.
What is false about points?
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.
How do you turn a liquid to gas?
Heat it past its boiling point.
