Discover the role played by intermolecular forces in changing the state of matter between solid, liquid and gas.
- Intermolecular forces are the attractive forces between molecules.
- Intermolecular forces determine whether a substance is a solid, liquid or gas.
- The size of the molecule and the distance between molecules affect the strength of the intermolecular force.
- Intermolecular forces are overcome when a substance changes state.
All matter is made of particles that are far too small to see.
These particles are in constant motion, and are attracted to each other.
The attractive forces between molecules are called intermolecular forces.
These are what determine whether a substance is a solid, liquid or gas.
Unlike the strong covalent bonds that …
