This question is dependent on pressure. Many things that cannot ordinarily be melted, can be liquefied if there is sufficient pressure applied. Water does not melt if the pressure is low enough. Some things that do not ordinarily have a liquid state are:
- carbon dioxide
- Iodine
- methane
- ammonium
Substances like diamond and graphite cannot be melted because they have extremely high melting points or undergo sublimation directly from solid to gas. Additionally, plastics which are made up of long molecular chains can degrade and break down instead of melting when exposed to high temperatures.

An example of physical change that is irreversible?
A potato that has melted cannot look like what it was again.
Why melted wax don't conduct electricity?
Melted wax does not conduct electricity because it is an insulator. Insulators do not allow electricity to flow through them because the electrons in the material are tightly bound and cannot move freely to conduct an electric current. This makes melted wax a poor conductor of electricity.
Can you reverse the melting of ice?
No, once ice has melted, it cannot be reversed back into its solid state without the application of freezing temperatures or other methods of solidification.
What is the word for melted iron?
The word for melted iron is "molten iron."
Is copper a thermosetting plastic?
No, copper is a metal and not a thermosetting plastic. Thermosetting plastics are a type of polymer that, once cured, cannot be melted or reshaped due to the crosslinking of their molecular structure. Copper, on the other hand, is a malleable metal that can be melted and reshaped.
How to melt cement?
Cement cannot be melted as it is a bonding agent that hardens when mixed with water. Once cement has cured, it cannot be melted back into a liquid state.

A potato that has melted cannot look like what it was again.
What do you call compounds that conduct electric currents when dissolved or melted?
When dissolved or melted you would call them ionic. However you cannot then be absolutely certain that the solid is a straight forward ionic solid!
How do you melt the snow drift on club penguin?
No You Cannot Melt It Becuase I Have Tryed Myself The Snow Drift Or Most Call It (Iceburg) Cannot Be Melted
Can glass be made of coal?
glass is melted sand, therefore as far as i know, cannot be made of coal.
Why doesnt the metal bucket melt when carrying melted metal?
Their the same thing, only melted. The molten metal is hot, but the only things metal cannot carry is something at the temperature of lava or higher.
What does the melted ice cube do in pajama sam?
In Pajama Sam, the melted ice cube acts as a key to unlock the jail cell where the carrot is being held. By using the melted ice cube to freeze the door's lock, Pajama Sam is able to open the jail cell and free the carrot.
Where is a six sided planet?
Planets cannot form with six sides; if they did, the corners and edges would be quickly scraped and melted off.
Is melted plastic bad?
Yes, melted plastic is harmful to health and the environment. When plastic is melted, it releases toxic fumes that can be dangerous if inhaled. Additionally, melted plastic can contaminate the surrounding area and leach chemicals into the soil and water. It's important to avoid melting plastic and dispose of it properly.
What is it called when you have plenty of water you can't drink?
When you have plenty of water you cannot drink it is frozen water, or ice. However, as scientific points and to add a mental challenge, we can also say all ice can be melted with the right conditions, but not all melted ice can be drunk.
Why does the electrical conductivity of ionic compounds change when they are melted or dissolved in water?
The electrical conductivity of ionic compounds increases when they are melted or dissolved in water because the ions are free to move and carry electric charge. In the solid state, the ions are fixed in place and cannot conduct electricity. When melted or dissolved, the ions are able to move freely and carry electric current.
Where did the first rain come from?
When comets pounded into young Earth, they carried ice. The ice melted and formed water. Where it rained first cannot be found out.
