Solid Naphthalene Crusher In Kazakhstan

Explain how solid naphthalene in mothballs is distributed evenly through clothes in a drawer. It undergoes sublimation where it is converted from solid to gas. Once it becomes a vapor, it can diffuse throughout the drawer as gases tend to occupy the entire space of the container.

A spherical ball of solid, nonporous naphthalene, a "mothball," is suspended in still air. The naphthalene ball slowly sublimes, releasing the naphthalene vapor into the surrounding air by the molecular diffusion-limited process. Estimate the time required to reduce the diameter from 2.0 to 0.50 cm when the surrounding air is at 347 K and 1.0 ...

1. Thermodynamics of Solid-Vapor Equilibria The solubility of a nonvolatile solute in a super-critical gas is determined from standard thermody-namics16}. Solid-vapor equilibria considered in this study are those for which the solid phase is assumedto be pure solute (component 1) and the vapor phase is a

When used as a moth repellent, solid naphthalene in the form of mothballs or flakes is typically placed in closed drawers, closets and plastic bags where clothes, blankets and other goods are stored. However, this product is sometimes more broadly applied as general insect and animal repellent by placing it on trays or other surfaces in rooms ...

A stream of air at 100kPa pressure and 300 K is flowing on the top surface of a thin flat sheet of solid naphthalene of length 0.2 m with a velocity of 20 m/s. Given information: Kinematic viscosity of air (v)=1.5×10−5 m^2/s Mass diffusivity of naphthalene vapor in air (DAB )=6×10−6 m^2/s Concentration of naphthalene at air-solid ...
