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.
Is freezing chemical or physical property?
I would say that freezing point is a boiling property because there is no scientific evidence to suggest that it is or indeed ever will be a chemical property. Freezing point is a chemical reaction. Therefor this is a debatable question. Different people may have different views. This is mine."Freezing point" is usually termed as "melting point" in scientific circles. Melting point is defined as the temperature at which the solid and liquid phase of a substance coexist at equilibrium under the pressure of their own vapors. Ice and water coexist at equilibrium at temperature of 32 degrees F when only their own vapor pressures are acting upon them. However, the temperature difference at atmospheric pressure is negligible. As you can see, melting point (freezing point) only depends on the physical conditions acting on the substance, therefore, melting point (freezing point) is a physical property. Melting point is effected (lowered) by the addition of other molecules or ions to the substance. This effect is physical because it depends only upon the number of particles (molecules etc) added and no chemical reaction is required.
At room temeperature a substance with a melting point of 40 degrees celsius is?
know you then, only one substance 40 degress celsius melts, yes?
What is a calcinatory?
A calcinatory is a vessel used in calcination - the act of heating a substance to a high temperature below its melting point in order to bring about thermal decomposition.
What becomes solid above the melting point?
assuming it is its own melting point NOTHING which is why its a MELTING point
How can you determine if a substances is a solid at room temperature?
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.

What is a melting point A freezing point?
melting point is the temperature it has to be to melt. Freezing point is the temperature it freezesThe melting point is the temperature above whichsomething will melt or be in a liquid state.The freezing point is the temperature below whichsomething will be in a frozen or solid state.The actual melting point, which is also the freezing point, is the temperature at which matter can exist as either a solid or a liquid at the same time and can change from one to another until its temperature goes up or goes down.
Is the temperature of the stiffer mantle above of below its melting point?
is the temperature if the stiffer mantle above or below its melting point
How is the melting point of a substance related to its freezing point?
The melting point of a substance is when a substance turns from a solid to a liquid, and the freezing point is when a substance turns froma liquid to a sold. This of water, t he freezing point, when it turns to a solid (ice) is 0 degrees C. Hope that helps!
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

At room temperature a substance with a melting point of 40 Celsius is a?
Room temperature is 25 oC so it would still be a solid. It would be 104 degrees F... So. unless the substance's boiling point is below that, it would be a solid. otherwise it would be a gas.
What is the melting temperature of metal?
The melting temperature of metal varies depending on the specific type of metal. For example, the melting temperature of iron is around 1,538 degrees Celsius, while the melting temperature of aluminum is around 660 degrees Celsius.
At room temeperature a substance with a melting point of 40 degrees celsius is?

Is the stiffer mantle above or below the melting point?
is the temperature if the stiffer mantle above or below its melting point
Does the melting point of a substance is below the room temperature?
Question does not make sense. please re-phrase so we can understand what you are trying to get across. Thanks!
