What is a crystalline solids melting point?
Name this crystalline solid; each compound and material have a different melting point.
Why urea has sharp melting point but glass does not?
Urea is a pure crystalline compound so has a sharp melting point while glass is an amorphous mixture.
Why two different compound have different melting points?
because the arrangement of molecules are different in both.
What is the melting point for grass?
Applying heat to grass will not cause it to melt but to burn. Glass is a silica compound that due to the addition of soda softens at about 1500 °C (2700 °F) It is not a true "melting point" since amorphous solids do not have sharp melting points like crystalline solids do.
Why amorphous solids do not have sharp melting points while crystalline solids do have?
in crystalline solids, the atoms are arranged in an ordered fashion and hence they have sharp melting points. amorphous solids, due to random arrangement of the atoms do not have sharp melting points.
What is a crystalline solids melting point?
Name this crystalline solid; each compound and material have a different melting point.
Why urea has sharp melting point but glass does not?
Urea is a pure crystalline compound so has a sharp melting point while glass is an amorphous mixture.
Which factor has the greatest effect on the melting point of a crystalline solid?
The factor that has the greatest effect on the melting point of a crystalline solid is the type of bonding among the particles. Heat breaks the bonds that hold the particles together.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
Why two different compound have different melting points?
because the arrangement of molecules are different in both.
What physical change of a solid to a liquid at the melting point?
The physical change of a solid to a liquid at the melting point called melting.
How is melting different from evaporation?
Melting is the process when a solid changes into a liquid, whereas Evaporation is the process when a liquid changes into a gaseous state E.G Melting - Ice -> Water Evaporation - Water -> Vapor MELTING- ice-gas no
What is the melting point for grass?
Applying heat to grass will not cause it to melt but to burn. Glass is a silica compound that due to the addition of soda softens at about 1500 °C (2700 °F) It is not a true "melting point" since amorphous solids do not have sharp melting points like crystalline solids do.
Why will it still have a melting point range although a crystal may be pure?
because each compound has different isomers so that is why the melting point range is different.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
What is a list of the characteristics of a crystalline solid?
when a crystalline solid such as snow is heated its melts at a destined characteristic melting point
Does a crystalline solid has a definite melting point?
Yes, it is true.
