States of Matter Jun Ruan Solid Molecules are tighly packed and harder than liquids and gases. Examples: Ice‚ Coal‚ Salt Amorphous solid-a solid which has a disordered atomic structure. Examples: Glass‚ Rubber Liquids flowing freely but of constant volume. Examples: Water‚ Mercury‚ Alcohol Viscosity-a measure of its resistance to gradual deformation by shear stress or tensile stress. Surface tension-the force that acts on the surface of a liquid and tends to minimize the surface

Why English-only policy would not work? What would happen to America if immigrants could not speak their native-languages anymore? The use of languages other than English stimulated a movement known as “English Only Movement” in the U.S‚ which has been a subject of great controversy. On one hand‚ the pro English only agree it would encourage immigrants who do not speak English to learn it; therefore‚ it would turn them Americans bringing the U.S together as a whole. On the other

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is

Case: BRITA- In search of a winning strategy Some of the challenges that Brita faces are as follows: • Decline in sales since 1998. As company’s flagship brand‚ Brita was expected to contribute double digit top line growth. But in reality‚ there was approximately a 5% decline in sales every year since 1998 and this decline continued until 2006. • Faced the problem of losing customer faith in the Brita brand. Brita had slowed established a string brand position among consumers over the ten year

attention and affection XXXX. The effects of "dethronement"‚ or lack thereof in the case of only children‚ determine such personality traits as responsibility‚ attitudes toward authority‚ self-esteem‚ and achievement motivation. According to this theory‚ oldest children are significantly different from youngest children because the first-borns suffer the effects of dethronement while the youngest children do not. Only children possess the characteristics held by first-borns before their "dethronement" occurred

Nicholas G. Carr published this article in the May of 2003. Its purpose was to convey to the reader that IT no longer matters and may no longer be relevant. Carr’s reasoning behind this is that corporations have universally accepted and use IT; this makes the use of IT a commodity and no longer puts the corporation at an advantage over any other using IT. Which means that using IT would no longer be a strategic decision for the corporation. After explaining this Carr offered new rules for IT management

CHAPTER 5 STATES OF MATTER INTERMOLECULAR FORCES Intermolecular forces are the forces of attraction and repulsion between interacting particles (atoms and molecules). Attractive intermolecular forces are known as van der Waals forces. van der Waals forces include dispersion forces or London forces‚ dipole-dipole forces‚ and dipole-induced dipole forces. A particularly strong type of dipole-dipole interaction is hydrogen bonding. Dispersion Forces or London Forces Observed between non-polar molecules
