Atmospheric pressure is simply a measured value. Several branches of science might need to measure the atmospheric pressure. A physical chemist who is doing gas-phase experiments may need to measure the air pressure. A synthetic chemist, trying to optimize his reaction might need to worry about the pressure.. Atmospheric chemistry is the study of the chemical processes that occur in the atmosphere, and it includes the underlying chemistry that governs air pollution and global climate change from the gases and particles emitted into the atmosphere.. Abstract. This chapter provides a literature review and a critical commentary of the available evidence on pharmacological treatment of tics in Tourette syndrome (TS). Because of the waxing and waning nature of tics, a meaningful appraisal of treatment efficacy in TS can only be given in most cases after a longer observation time.

Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid. Freezing Point Definition – The Freezing point is the temperature of a liquid at which it changes its state from liquid to solid at atmospheric pressure. At freezing point, these two phases viz. liquid and solid exist in equilibrium i.e. at this point both solid state and liquid state exist simultaneously. Atmospheric pressure affects the weather phenomena. If the air current is cold, it lowers and raises the pressure, contributing to the formation of what is known as thermal anticyclone. On the other hand, if the air is warm or hot, it increases and promotes a drop in pressure, which leads to the formation of a thermal cyclone and causes.
