In the world today‚ Nicotine is one of the most frequently used addictive drugs. The impact it has on society is like no other. It is one of more than 4‚000 chemicals found in the smoke of tobacco products such as cigarettes‚ cigars‚ and pipes. This addictive drug is the primary component in tobacco that acts on the brain. Tobacco can be found two ways‚ it can be dried brown leaves of various sizes or it can be a grown form of tobacco. When extracted from the leaves‚ nicotine is colorless‚ but

3.7. Dielectric Studies Dielectric properties are the complex function of bulk permittivity‚ conductivity‚ size‚ shape‚ frequency and spatial arrangement of the constituents [27]. The Dielectric complex permittivity is written as where‚ the real part εr and imaginary part ε″ are known as dielectric constant and dielectric loss accounts for the energy storage and energy loss respectively. The dielectric constant is calculated with the relation εr=Cd/εoA where‚ C is series capacitance

Colligative Properties & Osmotic Pressure (Lab – Chapter 13) Introduction: In this lab‚ we are going to observe the difference in freezing point between pure water and salt water. We will also observe the permeability of an egg shell membrane and dialysis tubing‚ acting in place of a human cell‚ when placed into a hypertonic or hypotonic solution. We will observe the changes in size‚ shape‚ and characteristic. Materials and Methods: First we begin this experiment by making an ice bath in

also for curing purposes. The chemical reaction of cement and water‚ in the mix‚ is relatively slow and requires time and favorable temperature for its completion. Depending on the quality and proportions of the ingredients used in the mix‚ the properties of concrete has enough strength in compression‚ but has little strength in tension. Due to this‚ concrete as such is weak in bending‚ shear and torsion. Hence the use of plain concrete is limited to applications where great compressive strength

Surface Tension Properties of Liquids Introduction The purpose of this experiment is to measure and record the surface tension of water and other aqueous solutions using capillary rise method techniques and practicing lab safety. In this laboratory the surface tension of water depends on the concentration of the following solutes; NaCl‚ acetone‚ and sodium dodecyl sulfate (SDS). Intermolecular interactions as well as other phases (solid‚ or air) make a liquid exist. The data collected will show
