interior of the Sun. The visible surface‚ chromosphere‚ and corona make up the exterior of the Sun. 2. What is nuclear fusion? What role does nuclear fusion play in the Sun? Nuclear fusion happens when two atomic nuclei combine to form one heavier nucleus. Since the majority of the atoms at the core of the Sun are ionized‚ the nuclei and electrons are stripped from each other in the heat. About 75% percent of these nuclei are hydrogen and about 25% of the nuclei at the core are helium.The nuclei occasionally

become so creative that they are inventing these products that consumers are able to put to daily use. After seeing exactly how bizarre some of these items are‚ you can’t help but ask if their creators intended them for serious use. How does a scoop of ice cream sound on a motorized cone? How about a bra with its very own built in wine rack? The number of people putting these items to daily use may actually shock you. Have you ever been told by someone to go eat crap? Well it is now possible. After purchasing

Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy D. F. Nachman 6/23/2010 Abstract: An ice calorimeter was used to study the reaction of magnesium metal and 1.00M sulfuric acid solution: Mg(s) + H2SO4(aq) →MgSO4(aq) + H2(g). We found the experimental molar enthalpy of reaction to be ΔH = –355 ± 17 kJ/mol at 0°C‚ 24% lower than the textbook value of ΔH° = –466.9 kJ/mol‚ reported at 25°C. Introduction Whether a chemical reaction occurs spontaneously or is driven by an outside

Sour Grape Ice Cream 1 WRITTEN ASSIGNMENT: SOUR GRAPE ICE CREAM Ice cream is just ice‚ fat and air; the way these three main ingredients interact determines the ice cream quality. Color‚ texture and taste are the main quality factors for ice cream. To optimize these it is particularly important to control process parameters including the temperature and time of heating and cooling the mixture. Over-heating and slow cooling causes changes to the flavor and color of the milk‚ whereas under-heating

Sam Wood‚ a respected police officer in Wells‚ South Carolina‚ patrols the city every night. One night‚ after stopping at his usual diner for a snack‚ and discussing Negros unfavorably with Ralph‚ the night counterman‚ Sam finds a body in the middle of the highway. He reports the body‚ which is soon tentatively identified as that of Maestro Enrico Mantoli‚ the conductor and lead organizer of the city’s upcoming music festival. Bill Gillespie‚ the chief of police‚ is notified‚ and after his arrival

* . Introduction Endothermic reactions are accompanied by the absorption of heat. The dissolving of ammonium nitrate in water is an example of an endothermic reaction. The solution resulting from this mixture is colder than either the ammonium nitrate or the water. This is the simple explanation of what happens in an instant ice pack. The more detailed information will be discussed in the following paragraphs. Cold Packs Most cold packs come with a fabric cover made to absorb condensation and

Until the 1960s‚ the radio was the only significant electronics in an automobile. All other functions were entirely mechanical or electrical‚ such as the starter motor and the battery charging systems. There were no “intelligent safety systems‚” augmenting the bumper and structural members to protect occupants in case of accidents. Seat belts‚ introduced in the early 1960s‚ were for improving occupant safety and actuated completely mechanically. The driver or one of several mechanical control

In nuclear chemistry‚ nuclear fusion and nuclear fission are different types of reactions that release energy due to the presence of high-powered atomic bonds between particles found within a nucleus. In fission‚ an atom is split into two or smaller‚ lighter atoms. Fusion‚ in contrast‚ occurs when two or smaller atoms fuse together‚ creating a larger and heavier atom. In both reactions‚ large amounts of energy are produced‚ with the only difference that fusion generates three or four times more energy
