CHM310H1 Lecture Notes - Lecture 9: Snowflake, Number Density, Nucleation
Document Summary
This could be the starting velocity of an aerosol. Any particle smaller than this would be that. If the winds keep moving the air around, they will be mixed aroud =, drifted: this is not a good way of removing the prticles, specially if it is small ones. For big ones it is a god way: particles which are 10 microns will get settled down by gravitation. Lots of acid rains comes from a dirty coal that has s in it. It"s the smallest particles to exist, in nanometers: they are formed by gas - to - particle conversion. So this can be 1 nm: there are particles that are few microns in size. These particles could be very few nm in size: there is mechanically formed particles, and from gases condensation together to dust formation, this is what gives rise to the overall sixe distribution to the particles int eh atmosphere.
