05.09 Module Five Review and DBA 05.01 Four Phases of Matter * Matter exists in different phases‚ also called states‚ which include solid‚liquid‚ gas‚ and plasma. These phases can be distinguished at the molecular level by how the particles are held together. * Solids * In the solid phase‚ the intermolecular attraction between particles of matter is strong enough to hold all the particles together in a fixed three-dimensional arrangement. Because of the rigid arrangement of particles

Kelsey Choquette Derek Thiess Research Essay 30 November 2010 High Fructose Corn Syrup and Obesity High fructose corn syrup (HFCS) is one of the major caloric sweeteners used in the food industry today. It is a sweetener that contain fructose and all provide 4 kcal per gram (Suzan‚ 620). It is relatively inexpensive to produce‚ so the food industry sees HFCS an easy way to make products less expensive. HFCS is a kind of corn sugar; it is nearly identical to sucrose (table sugar)‚ which
