Question
The ___________the forces of attraction between the particles, the ______ energy is needed to overcome them.
- Stronger, lesser
- Lesser, lesser
- Stronger, more
- More, More
Hint:
The stronger the force of attraction, the closely the particles are bound.
The correct answer is: More, More
- The force of attraction that combines two molecules or matter is intermolecular force.
- It is attractive in nature.
- The intermolecular forces vary for solids, liquids, and gases.
- The stronger the forces of attraction between particles, the more energy is required to overcome them.
