PPT-Cryogenic Safety All cryogenic liquids are gases at room temperature and atmospheric pressure.

Cryogenic liquids are materials with boiling points of less than 73 C 100 F What are Cryogenics Cryogen Background When stored and used properly cryogens are safe If stored improperly or misused cryogen can be dangerous and even kill you. Diffusion plus Convection. ).  . Molecular Diffusion in Gases. Equimolar. . Counterdiffusion. A. B. B. A.  .  . In terms of mole fraction, . Molecular Diffusion in Gases. Uni. -component Diffusion. Chemistry—2. nd. semester. Properties. All gases share some physical properties:. Pressure (P). Volume (V). Temperature (T). Number of moles (n). These properties combine to describe the behavior of gases using the “gas laws”. Atmospheric pressure. Pressure. Why do predators often have . SHARP . teeth and claws?.
