MOTOR TEMPERATURE RATINGS A frequently misunderstood subject related to electric motors is insulation class and temperature ratings. This paper tries to describe‚ in basic terms‚ the temperature relationships that are meaningful in standard AC induction motors. Some of the same information can be applied to DC motors but DC motors are more specialized and some of the ratings are slightly different. Perhaps the best way to start is to define the commonly used terms. MOTOR SURFACE TEMPERATURES

Aqueous Solutions Reactions‚ Metathesis (Double Replacement) Reactions and Net Ionic Equations Terrance Shelton Introduction India’s cultural treasure and biggest tourist attraction is slowly losing its magnificent appeal due to decades of acid rain. The walls of the Taj Muhal are composed of a marble-like substance ( CaCO3) that corrodes and eventually crumbles when reacted with acid rain(H2SO4). Not only is the Taj Muhal suffering‚ but also other historic landmarks across the world. This is

December 14‚ 2010 Conductivity of Ionic solutions Introduction This lab report is about the conductivity of ionic solutions. In class we have been discussing wether all ionic solutions conduct equally well. If an solvent solution conducts electricity‚ then it must contain ions. So measuring the conductance of solutions can tell you whether the solutes in the solution are dissociated into ions. (Conductivity) Any type of solution‚ even ionic solutions‚ provide resistance to the flow of current

SOLUTION AND CONCENTRATION A solution is a homogeneous mixture‚ made up of a solute dissolved in a solvent. Ex. In a water (aqueous) solution of sodium chloride‚ the sodium chloride is the solute and the water is the solvent. Solute – the component that is dissolved or is the least abundant component in the solution. Ex. Sugar‚ salt Solvent – the dissolving agent or the most abundant component in the solution. Ex. Water Common Types of Solution State of Solution State of Solute

stomach acid to alleviate indigestion. Alka-Seltzer tablets contain Aspirin‚ Citric Acid (CH3COOH)‚ and Sodium Bicarbonate (NaCO3). When the tablet is placed in water it undergoes an acid-base reaction and Carbon Dioxide (CO2) is a byproduct that causes the notorious “Fizz”. The objective of the lab was to measure the % of NaCO3 in an Alka-Seltzer tablet in different measures of an acidic solution (Vinegar). Through understanding of stoichiometric relationships and limiting reactants‚ quantities of
