What name is given to the attractive forces between molecules of the same type?
AAdhesive forces
BBuoyant forces
CCohesive forces
DShearing forces
Answer & Solution
Correct answer: C. Cohesive forces
1. Attractive forces between molecules of the same type are cohesive forces.
2. They are what holds a liquid together in an open container.
3. Adhesive forces act between molecules of different types instead, such as water and glass.
4. A buoyant force acts on a whole body and a shearing force is a sideways force, so neither describes attraction between like molecules.
