Do liquids have melting points?
No, they only have freezing points & gaseous points (it where the liquid becomes a gas). Why don' they have melting points? Well take this as an example: If you left your chocolate bar out in the sun it will melt and become a liquid. There for becoming a liquid IS melting, there is no further melting points to an object ounce it becomes a liquid. Substances have melting points. The melting point is the temperature at which a solid becomes a liquid, in other words, the temperature at which it melts.
How is boiling point and melting point related?
Boiling points and melting points are temperatures at which change of phase occurs to liquids andsolids. Some substances, such as water, have a TRIPLE POINT temperature at which all three phases (solid, liquid, vapor), exist simultaneously.Boiling point of a liquid is the temperature at which its phase changes into vapor and the melting point of a solid is the temperature at which it changes state from solid to liquid. The solid and liquid phase of a substance exist in equilibrium at the melting point. The reverse change from liquid to solid is referred to as the freezing point. The freezing point of a substance is often determined by observing the temperature at which a solid begins to change into a liquid, which is actually the melting point, because a characteristic property of some substances is their ability to supercool.
What is the melting temperature of metal?
Melting temperature is the point where a substance is reduced to a liquid (this is the state it changes to). the usual melting point of substances is 100 degrees or higher.
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.
The temperature at which a substance becomes a liquid?
It is different for different substances. the generic name for the temperature at which a solid becomes a liquid is the melting point. For a pure chemical compound or an element this is usually a sharp temperature rather than a range.
What temperature do liquids turns into solids?
That temperature is known as the melting point. It is different for every substances.
When solid changes into liquid?
Solids changing to liquids are melting Liquids changing to solids are freezing Solids changing to gas are subliming Liquids changing to gas are boiling Gases changing to liquids are condensing.

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 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
What is the substances melting point the same as?
The freezing point is the same as the melting point, temperature-wise.
What characteristics do ionic liquids have?
Such liquids have high density, good electrical conductivity and become solid as temperature decreases from their melting point.
How does a substances melting point determine its state at room temperature?
If the melting point is under 20 oC the substance is a liquid.
What are some things that have melting points?
All substances have a melting point.Water, for example, has a melting point. It is simply the temperature at which a substance changes states to a liquid.
What element remains solid in warm and remains liquid in cold temperatures?
There is no such element as this is physically possible. The liquid state is only achieved when the temperature has reached the melting point of the material. And, the melting point is, by definition, at a higher temperature than the freezing point. However, there are substances that are liquids in cold temperatures (many oils) as well as substances that are solids in warm temperatures (most metals); but this does not mean that the oils do not freeze and the metals do not melt.
How and why do substances change volume when their temperature changes?
because of the set melting and freeZing points
