What change of state is taking place when molten steel from a furnace is poured into a mould?
When molten steel is poured into a mould, it undergoes a change of state from a liquid to a solid. As the molten steel cools, its temperature decreases, allowing the metal atoms to bond and arrange themselves into a solid structure. This process is known as solidification or freezing, resulting in the formation of a solid steel object.
How does molten lava change into a solid?
Molten lava cools down and solidifies into solid rock through a process called solidification. As the lava loses heat, the atoms and molecules within it slow down and come together to form a crystalline structure, which results in the formation of solid rock.
What things can solidify?
Solids can form from liquids through a process called solidification or freezing. Common examples of substances that can solidify include water into ice, molten lava into rock, and molten metal into ingots.
What temperature does salt solidfy?
Salt, specifically sodium chloride (NaCl), does not have a distinct freezing point like water; instead, it begins to solidify at around 801 degrees Celsius (1474 degrees Fahrenheit) when cooled from a molten state. In solution, salt can also crystallize out of water as the temperature decreases, typically happening at lower temperatures when the solution becomes supersaturated. However, the solidification of salt itself happens at much higher temperatures than typical environmental conditions.
Why does molten rock turn red?
Molten rock glows red because it is extremely hot. Glowing due to high temperature is called incandescence.
What is the freezing point of molten candle wax?
range from 47oC to 81oC
What temperature is molten metal?
It depends on the metal. As an example mercury (Hg) is liquid or molten at room temperature. Gallium becomes molten at just slightly above room temperature. Tungsten on the other hand has a very high melting temperature.

What happens if you put fire on glass?
It depends, if the temperature is right then the glass will melt become more molten/liquid, or depending on the glass if it is brittle and is brought to experience a change in sudden temperature (i.e. from freezing cold to boiling hot and vice versa) it will shatter.
What can you do with frozen salt?
Technically all table salt is "frozen" because it is in the solid state. If you stick it in the freezer it gets cold but nothing happens. The freezing occures when it goes from a molten state to a solid. When dissolved it is considered aqueous solution.
What happens when NaCl is heated?
If you heat it to 801 degrees Celsius, it melts.
What color is molten gold?
Molten gold is a bright, shimmering yellow color due to its high temperature, around 1,948 degrees Fahrenheit.
What is the molten layer of the earth where convection happens?
no it happens on the surface of earth i think . Good luck!
What happens to atoms when cooled?
as the atom cools down it comes back in its orignal shape .it will be in its contracting form
What happens molten material cools?
It depends upon the material. Some material (such as most metals) has a distinct freezing point, a temperature where it changes directly from a liquid to a solid. Other material (such as glass) has no distinct temperature at which it will solidify. As it cools, it keeps getting less and less fluid, but never freezes. If its temperature is low enough, it will arrive at a state which is for all practical purposes a solid.
