Beta decay occurs when the neutron to proton ratio is too great in the nucleus and causes instability. And gamma decay occurs when the nucleus has too much energy. 3. What is meant by nuclear fission? Nuclear fission is a nuclear reaction that produces a lot of energy, and occurs when the nucleus of an atom splits into two parts spontaneously or with the impact of another particle.
Nitroglycerin breaks down after being pressurized or exposed to heat. The balanced equation for when nitroglycerin combusts is 2C3H5(NO3)3 <--> 6CO2 + 5H2O + 3N2 + O2. Sometimes, dynamite can be closely related to TNT, although they aren’t much alike at all. Nitroglycerin should only be worked on when the substance is a liquid. If it is not, the frozen or semi-frozen state of the product is quite dangerous to handle.
Abstract The process of nuclear fission causes the formation of fission products. The source and quantity of byproducts of fission are explained to provide a foundation for a discussion of the effects of fission products. The swelling effect of both solid and gaseous byproducts of fission is explained and the negative effect that swelling has on fuel performance as well as its limiting affect on burnup is described. Finally, potential solutions to deal with the effects of fission products and subsequently allow for increased burnup are discussed. Introduction The quantity of fission products in a nuclear reactor is dependent on the amount of fission occurring, which is directly related to fuel burnup.
On top of this, the helium nucleus is clearly labeled and is shown containing two neutrons and two protons (which are also labeled using an “N” and a “+”). Similarly, my model of beta decay is labeled in the same manner as that of the alpha decay model. In beta decay, an unstable atom uses its natural tendency to become stable to “transform” one neutron into a proton. Subsequently, the new positive charge requires an electron to be released from the atom’s orbit. This process is shown clearly in my model due to the fact that it states that the atom gets the energy to carry out this process from the instability of itself.
Therefore, the boiling points and melting points are greater because more energy (through heat) is needed to break the bonds. The van der Waal forces will also aid in the identification of an unknown. These forces are dipole-dipole and dispersion, the latter being the weakest of the intermolecular forces. Although not as strongly bonded as the hydrogen bond, the it takes a high amount of energy to break them apart, causing high melting and boiling points. Molecular weight influences how strong the intermolecular forces can be.
The middle layer is a group of laser beams. And the inner layer is nanotubes that protect structures from laser beams. Later he argues the lasers will destroy objects, which the lasers will go that get through the force field. To fix that problem Kaku thinks that the force field needs to have photochromatics. Then Kaku states that force fields can do more than deflecting laser beams because it can levitate objects by the use of magnetic force fields.
Antiferromagnetism: In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions. This is, like ferromagnetism and ferrimagnetism, a manifestation of ordered magnetism. Generally, antiferromagnetic order may exist at sufficiently low temperatures, vanishing at and above a certain temperature, theNéel temperature (named after Louis Néel, who had first identified this type of magnetic ordering).  Above the Néel temperature, the material is typically paramagnetic. * Antiferromagnetism materials: Antiferromagnetic materials occur commonly among transition metal compounds, especially oxides.
Nuclear fusion combines nuclei to produce energy and it creates four times as much energy compared to nuclear fission, which is the current form of commercialised nuclear power. In nuclear fusion, it has been tested with reactions of hydrogen isotopes; deuterium and tritium however; it gave off the majority of its energy as radioactive neutrons which is quiet hazardous and raises safety concerns. In contrast, when helium-3 reacts with deuterium it produced low levels of radioactivity and is perfectly safe as it does not give off any pollution or radioactive waste. Therefore, it shows no danger to surrounding areas. By having helium-3 as the next power production on earth it will also decrease the amount of pollution and radioactive waste in the atmosphere.
Although it contains small amounts of various other gases, it is mostly made of Hydrogen and Helium. Gravitational collapse pulls the Nebula together flattening it into a disk shape called a protoplanetary disk. This process starts slowly but speeds up as material is pulled in. A slightly unbalances force pulling the material causes it to spin. This spinning motion makes the nebula forma bulge of Hydrogen and Helium in the center known as a protosun.
Fractional distillation is the separation of a mixture into its component parts, or fractions, such as in separating chemical compounds by their boiling point by heating them to a temperature at which several fractions of the compound will evaporate. It is a special type of distillation. Different types of hydrocarbons are obtained from the fractional distillation of petroleum. Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst.
