Describe the collision- coalescence process

• In the collision-coalescence process, cloud droplets evaporate completely
• The collision-coalescence process is a mechanism by which cloud droplets collide and combine to form larger droplets.
• The collision-coalescence process involves the separation of cloud droplets into smaller particles
• Collision-coalescence is a process where cloud droplets freeze instantly
