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

1 answer

A particle with jagged, rough ends would generally have a higher rate of deposition. This is because irregular shapes can increase the likelihood of collisions with surfaces and other particles, leading to a greater chance of settling. Additionally, rough ends can create increased friction and adherence to surfaces, further enhancing deposition.
