Particle Deposition Rate

Which particle has a high rate of deposition?

a low-density particle

a small particle falling off a cliff

a particle with jagged, rough ends

a large round particle settling on a surface

The particle with a high rate of deposition is a large round particle settling on a surface.

Particle deposition rate refers to the speed at which particles settle on a surface. In this case, the particle with a high rate of deposition is a large round particle that settles quickly on a surface.

When comparing different types of particles, larger particles have more mass and momentum. This makes them more likely to settle faster on a surface compared to smaller particles. Moreover, the round shape of the particle reduces air resistance, allowing it to move more efficiently through the air and settle faster.

For example, if you were to drop a large round rock and a small pebble at the same time, the rock would reach the ground first due to its higher rate of deposition.

Understanding particle deposition rate is important in various scientific fields, such as environmental science, chemistry, and physics. It helps in determining how particles behave in different environments and how they interact with surfaces.
