What is goals boiling and melting point?
Melting and boiling points are important characteristics of materials: they are needed in industry and in laboratory.
What has a low melting point and is useful in sprinklers?
modern automatic sprinklers use a glass bulb that is filled with a fluid that boils and expands at a preset temperature. the glass bulb has a small bubble in the fluid. when a fire causes the fluid to boil, it shatters the glass bulb, which is keeping the waterway seal of the sprinkler in place. When the seal is gone, water can flow through the sprinkler orfice, and extinguish the fire. older sprinkler models use a link and lever arrangement, with a link of solder that melts at a preset temperature. The link and levers of the sprinkler mechanically hold the waterway seal of the sprinkler closed. When the link melts, the mechanical seal is gone, and water can flow through the orfice.
Which ions have high melting points?
positive ions have high melting points
Do proteins have definite melting points?
Different proteins have different melting points.
Compared with the melting points of ionic compounds the melting points of molecular solids tend to be .?
Ionic compounds have a higher melting point.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
Where are the freezing points and melting points of gold?

What are the melting points for iron?
1535 degree melting of iron
Explain why there is this pattern in melting points for francium?
The melting point of francium is not measured, only supposed by comparison with the melting points of the other alkali metals.
