Andrea Moreno 4 September 2015 Block B Calculations: There are no calculations. Analysis/ Critical Thinking Questions: Compare your data for the pure substances with the data for each of the two solid mixtures. Which of the pure substances shows behavior that is similar to what you saw with the the two-solid mixtures (Mixture 1 and Mixture 2)? If you cannot positively identify your mixture‚ discuss the possibilities for the mixture. The starch and mixture 2 are both similar because they both did not

Determination of Cleansing Action of Detergents (Using Capillary rise) Synopsis This project report explains about the surface tension and capillarity of liquid through a simple experiment of finding the capillarity of various detergents. Oil stains and grease on dirty clothes cannot be removed‚ using water alone‚ because water does not wet them. If detergents added ‚ surface tension is decreased‚ the area of contact is increased

Who doesn’t love to read a good magazine? In Women’s Day there was an ad about Liquid Plumber‚ and good gracious there’s a sexy man on the cover. It quotes “Only have 10 minutes? I only need 7.” In the ad his name is Rusty‚ and he is well groomed. Rusty has a chiseled body his shirt tucked in; with just a little bit of chest hair sticking out. Those hip hugging blue jeans are a plus as well! His hair looks like it has been played with and he has a seductive smirk on his face. Most women would stop

BREAKDOWN IN SOLID DIELECTRIC The requirements of good dielectric: o Low dielectric loss‚ o High mechanical strength‚ o Free from gaseous inclusions‚ and moisture‚ o Resistant to thermal and chemical deterioration. Solid dielectrics have higher breakdown strength compared to liquids and gases. When breakdown occurs‚ solids get permanently damaged while gases fully and liquids partly recover their dielectric strength. Breakdown mechanism varies depending
