Dalton wondered how air and water could exist in the same space at the same time. He inferred that, if water and air were composed of different particles, then evaporation might be seen as a mixing of air and water particles. Dalton developed a hypothesis that the sizes of the particles making up different gases must be different.]]> 2021-09-28 20:28:07 UTC https://padlet.com/brookeottum/2qq7roze33ix4fpw/wish/1775886674
