Key Stage 2
Meaning
Melting is when a solid turns into a liquid.
- Verb: To melt
- Present Participle: Melting
About Melting
- Most solids can be melted to become a liquid.
- Melting is a reversible process. When a solid melts you can always freeze it back into a solid.
- You may have seen these solids melt
Examples
|
|
Some ice cubes melt to make water.
|
Wax melts because of the flame.

|
|
Chocolate can melt in your mouth because your mouth is warm.

- A solid can be melted by heating it.
Key Stage 4
Meaning
Melting is an endothermic physical change in which a solid turns into a liquid.
About Melting
- Melting happens when the particles in a solid break bonds holding them in fixed positions as they gain potential energy.
- The temperature at which a substance melts is called its melting point.
- Melting is an endothermic process, which means it needs to absorb energy to take place.
- Melting is a physical change, which means it is reversible and does not produce new chemicals.
