uses of isotopes

. This is known as ocean thermal energy. Small scale experiments have shown that it might be possible to build large ocean thermal energy systems but they would be quite expensive. Different seas have different concentrations of salt. When two seas meet, electricity can be produced by making u..

Relation Between Atomic Mass Unit and MeV (Mass Energy Relation) - The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u). 1 a.m.u is defined as 1/12 t h of the mass of an atom of 6 C 1 2 isotope. It can be shown that 1 a.m.u = 1.66 x 10 2 7 kg. Accord..

Summary - Hydrogen is the most abundant element in the universe. Hydrogen is also the lightest element in the universe. It has a vapour density of 1, which is 14.4 times lighter than air. Hydrogen is absent in the free state in the earth's atmosphere. But in the combined state it is found in water,..

.e., the equilibrium position) no movement of children on the see-saw occurs. Static Equilibrium In the case of reversible reaction, however a static equilibrium is not being established. In the case of ammonia, using deuterium, D (an isotope of hydrogen) it has been proved that..

The semi conservative DNA replication was confirmed by an elegant experiment conducted by M. Meselson and F. W. Stahl in 1958. They grew the bacterium Escherichia coli in a medium containing nitrogen salts labeled with the stable heavy isotope 1 5 N. 1 5 N was incorporated into both ..

Graham's law is useful in: Separation of gases having different densities by diffusion. Determining the densities and molecular masses of unknown gases by comparing their rates of diffusion with known gases. Separating the isotopes of some of the element..

Nuclear changes can be brought about by bombardment of nuclei with accelerated particles like neutrons, deuterons and protons. A particularly important process for the production of artificial radioactive isotope is the (n, g ) reaction, which is applied to synthesize new elements. ..
