What else can I help you with?
Why will it still have a melting point range although a crystal may be pure?
Even in pure crystals, the melting point range can still exist due to imperfections or defects in the crystal lattice. These defects can cause different parts of the crystal to melt at slightly different temperatures, leading to a range of melting points rather than a single sharp melting point.
What will be the melting point ice if it is kept under high pressure?
The melting point is not changed by pressure. It is still over 32O
How do you cool water to below the melting point and still have liquid water?

What is the melting point of alnico in Celsius?
300 degees C --- That's not even its curie temperature. Not only will it still be solid, it will still be a magnet.
Why naphthalene undergoes sublimation but has melting point?
Naphthalene undergoes sublimation because it has weak intermolecular forces that allow it to transition directly from solid to gas phase without melting first. However, naphthalene can still have a melting point due to the presence of a crystal lattice structure that requires enough energy to break to form a liquid.
Why is the boiling point lower than melting point?
The boiling point is lower than the melting point because during boiling, the intermolecular forces holding the molecules together are overcome, allowing them to escape into the gas phase. In contrast, during melting, the intermolecular forces are still present but being overcome to transition from solid to liquid.
What are the characteristics properties for a substance?
Depends on the substance. For example, table salt is generally a small, white, crystal with a cubic fracture, a melting point of 801 degrees C, a density of 2.164 grams per cubic centimeter, that is soluble in water and tastes salty.So unique properties of each substance may be different. Sugar is also a small, white crystal, but with a much lower melting point and a different taste.Arsenic has a similar melting point to salt, but you wouldn't want to taste it. Other properties might help you determine what it is (like density).But generally things like density, melting point, boiling point, specific heat and reactivity are things that you want to consider as characteristic properties for substances. Color, shape, even phase can easily change.Density is not very reliable because multiple substances can have the same density, but it is still considered a characteristic property.
Why can the boiling point and the melting point be used to help identify a substance?
The boiling and melting points are almost unique to individual substances. If it should happen that two possible substances have the same melting point, they can still be identified by the method of mixed melting points. If substances A and B have the same melting point and you mix them, the mixture will melt belowthe tabulated temperature. Thus if you mix your unknown with a sample of what you think it is, if you are right it will still melt sharply at the expected temperature, but if you are wrong it will melt gradually and at a lower temperature.
What is the lowest melting point of any metal not mercury?
Caesium melts at 28.44oC, which is the lowest known melting point for any metallic element other than mercury. Certain radioactive elements might have lower melting points if it were possible to collect a large enough quantity of them to actually determine the melting point. For example, the melting point of francium is expected to be lower than that of caesium (but still higher than that of mercury). Also, some alloys melt at low temperatures. A eutectic alloy of sodium and potassium melts at around -12oC, still higher than mercury, but below caesium (and well below either sodium or potassium alone as well).
Does crystal still have her crystal shop?
No
Is metal a liquid in room temperature?
No, metal is typically solid at room temperature. Some metals have melting points below room temperature, but they would still exist as solids at room temperature unless specifically cooled below their melting point.
What property does tungsten have that make it suitable for making filament?
Tungsten has a high melting point of 3422°C, which allows it to withstand the high temperatures produced when an electric current passes through the filament, without melting. This property helps the filament to emit light efficiently and have a longer lifespan.
