What is the name given to the change in state from liquid to solid?
When a liquid changes into a solid, it is called solidification.
When a solid melts does it absorb or give off heat?
From left to right, heat is absorbed from the surroundings during melting, evaporation, and sublimation. Form right to left, heat is released to the surroundings during freezing, condensation, and deposition.
What are the factors that causes the melting of the liquids?
Molecular composition, force of attraction and the presence of impurities can all affect the melting point of substances.
What are the factors that affects the melting point?
The force of attraction between the molecules affects the melting point of a compound. Stronger intermolecular interactions result in higher melting points. Ionic compounds usually have high melting points because the electrostatic forces holding the ions (ion-ion interaction) are much stronger.
What affects the melting and boiling points of a substance?
The stronger the forces of attraction, the more energy is required. Every substance has its own melting point and boiling point . The stronger the forces between particles, the higher its melting and boiling points. The strength of the forces between particles depends on the particles involved.
What are two examples of liquids?
Examples of Liquids
- Mercury (an element)
- Bromine (an element)
