Step 1:I'll solve this problem by providing clear examples of adhesion and cohesion from typical household observations:
Adhesion Examples:
Step 2:: Water Droplets on a Glass Window
- Adhesion occurs when water molecules stick to the glass surface - The water molecules are attracted to the glass surface due to intermolecular forces - This creates a thin film or droplets that cling to the glass, demonstrating adhesion between different materials
Step 3:: Paint Sticking to a Wall
- When paint is applied to a wall, the paint molecules adhere to the wall surface - The paint molecules form a strong bond with the wall material - This demonstrates adhesion between the liquid paint and the solid wall surface Cohesion Examples:
Step 4:: Water Droplets Forming a Spherical Shape
- Water molecules are strongly attracted to each other - These intermolecular forces cause water to form a rounded droplet - The water molecules stick together, resisting spreading, which is cohesion within the same material
Step 5:: Mercury Forming a Distinct Liquid Ball
- Mercury has extremely strong cohesive forces - When spilled, mercury forms a perfect spherical shape - The mercury molecules are strongly attracted to each other, preventing the liquid from spreading out
Final Answer
Adhesion Examples: 1. Water droplets on a glass window 2. Paint sticking to a wall Cohesion Examples: 1. Water droplets forming a spherical shape 2. Mercury forming a distinct liquid ball
