In air and according to Stokes Law, the settling rate of particles is proprotional to the squares of their diameters, if they have the same densities. If emitted particles with a given diameter are found to settle out after 7 days, how long would it take a particle of the same material with 1x the diameter to settle out?
Given the following reaction: 2 O2 + CH4 CO2 + 2 H2O What mass of CH4 is required to completely react with 100 grams of oxygen.
A certain minimum energy(E min) is required to eject an electron from a photosensitive surface. Any energy obsorbed beyond this minimum gives kinetic energy to the ejected electron.
A closed vessel contains moist air at 20 degree celcius, the relative humidity being 30 %. What would be the relative humidity become if the vessel were cooled to 10 degree celcius?
