Gas. How do particles move in a solid? . Solids . Have a definite shape/structure. Very little particle movement—fixed position. Liquids. Limited structure to particles. Option D. A variety of analytical techniques are used is used for detection, separation and analysis of pharmaceutical drugs.. These include. Chromatographic techniques. Capillary Electrophoresis. Infrared spectroscopy . Chapter 3. P-v-T diagram. P-t diagram (phase diagram). P-v diagram. T-v diagram. Compressed and saturated liquids. Compressed Liquid:. Water stays in the liquid form because it is being compressed. The atmosphere compresses it, and without it, it would all evaporate. (Without adding any heat).. Baker and Dash 1994. Karly Reimel. ATS 780. March 9, 2017. Baker et al. 1987. Looked at charge transfer to a rimed rod moving through a cloud in which liquid water, temperature, and collision characteristics were varied over ranges believed to be present within thunderclouds. Fundamental question: . How (why?) do cloud droplets form in the atmosphere?. Water vapor can supersaturate as “closed” air parcels rise and cool (or cool some other way, e.g. . radiatively. ). Will drops form as soon as relative humidity exceeds 100%?. H20 vapor plays a critical role in the atmosphere. Controls clouds and precipitation. Moves energy horizontally and vertically. Influences temperature. Major greenhouse gas. Need to have a deep understanding of its properties..
