Fission is a big nucleus breaking apart. Fusion is small nuclei combining, this releases more energy.…
Cold packs have a endothermic reaction that usually contains water and a packet of ammonium chloride. The Cold pack is activated by breaking the barrier separating the water and ammonium allowing the chemicals to mix. Once the cold pack is placed to the skin, energy is released keeping the cold pack reacting for a period of time. Endothermic reaction absorbs heat causing the cold pack to keep reacting until the cool of the pack is warm up to the surrounding area. Endothermic reaction is the opposite of exothermic reaction absorbing the surrounding heat. When the ammonium chloride reacts with water it has a chemical reaction that will give off a cold effect, when soaking up heat from the body.…
In the first part of the activity, observe a phase change for ice while measuring the temperature of the system. Use the Temperature Sensor to measure the temperature of a container of ice as small amounts of warm water are added to the ice. Use DataStudio or ScienceWorkshop to record and display the temperature data.…

Synthesis reactions occur to form a new solution out of two separate elements/compounds. There are many different types of synthesis reactions, each resulting in a different type of product. When these reactions occur, heat is often an energy that is deposited from the reaction.…

The two main forces involved in nuclear fusion are the electromagnetic force and the strong nuclear force. The repulsive electromagnetic force between positively-charged nuclei is long range but relatively weak while the nuclear force is short range but much stronger. When the two nuclei are far enough apart, the repulsive electromagnetic force dominates, holding the nuclei apart. As the two nuclei get closer the electromagnetic repulsion gets stronger and more difficult to push the nuclei together. When the two nuclei approach and get closer to each other, the nuclear force dominates and the two nuclei fuse together to form a new nucleus. This requires a lot of pressure, provided by gravity caused by mass to push nuclei together in short-range…
Nuclear fusion is a nuclear reaction in which two or more atomic nuclei such as Hydrogen or the isotope of Hydrogen (Helium) combine very close together and then collide at an extremely high speed to produce heavier atoms and energy. This type of reaction has not been commercially developed and only occurs in the sun and other stars in space.…
Nuclear energy uses nuclear fission to generate heat. Nuclear fission is where atoms are split apart which releases energy. All nuclear power plants use nuclear fission. Nuclear fission is where a neutron hits a uranium atom and splits it releasing a large amount of energy. More neutrons are released when a uranium atom splits hitting more uranium atoms. This is called a nuclear chain reaction.…
<br>Albert Einstein predicted that mass could be converted into energy early in the century and was confirmed experimentally by John D. Cockcroft and Ernest Walton in 1932. In 1939, Otto Hahn and Fritz Strassmann discovered that neutrons striking the element uranium caused the atoms to split apart. Physicists found out that among the pieces of a split atom were newly produced neutrons. These might encounter other uranium nuclei, caused them to split, and start a chain reaction. If the chain reaction were limited to a moderate pace, a new source of energy could be the result. The chain…
Many professors, scientists, researchers, and even governments, have been debating over the issue on the use of nuclear power as a main energy source. In Taking Sides, two authors who are highly narrow-minded state their debates on this critical issue. Allison MacFarlane, author of “Nuclear Power: Panacea for Future Energy Needs?”, believes that nuclear power should be revived. She argues that nuclear power will provide sufficient energy, while at the same time reducing carbon dioxide emissions. On the other hand, professor Kristin Shrader-Frechette, author of “Five Myths About Nuclear Energy”, argues that nuclear power is too expensive and unsafe for the environment, when there are renewable energy sources that are better for the environment and economy. I agree with Shrader-Frechette because she proves the five myths about nuclear energy wrong using extremely valid arguments, which exist to prove that nuclear power is not the best option for an energy source in our society.…
Low Energy Nuclear Reaction (LENR) is the abbreviation for an energy nuclear reaction that has low energy, in which the low energy nuclear reactions take place in the experiments such as room temperature that is close. They make nuclear-scale energy and nuclear products; however, they do not make harmful effects of the nuclear energy. Another word for the LENR, as researchers named it: “cold fusion.” The scientists however, proved through experiments and theories that LENR is not “cold fusion,” as the LENRs do not make long, lethal radiations. The practical definition of a LENR is that they are not based on any niche of fusion, but rather high, energetic reactions of nuclear that do not make any radioactive waste or radiation. The interesting fact of LENR is that it can make millions times the power of density of combustion energy process. It can create lots of small sized reactor heats for several months, by using a few amount of low level of fuel, in which it produces no threat of CO2. LENRs are weak connections that have the size of nanometer, if put on a surface.…
