Question
The substance which changes its states from solid to liquid is called
- Boiling
- Melting
- Evaporation
- Sublimation
Hint:
A physical process of phase transition.
The correct answer is: Melting
- When a solid is heated forces of attraction decrease.
- As forces of attraction decrease intermolecular space increases.
- A point is reached when forces of attraction overcome and the solid converts to liquid.
- The process of change of state from solid to liquid is called melting.
