Italian physicist

Italian physicist Alessandro Volta demonstrates the galvanic cell, also known as the voltaic cell. 

Italian physicist Allcssandro Volta creates the first continuous electrical current by making a battery out of silver and zinc strips placed in salty water. Prior to this discovery all man-made electrical sources came from static. 

Avogadro s law, referred to on page 107, was proposed in 1811 by an Italian physicist at the University of Turin with the improbable name of Lorenzo Romano Amadeo Carlo Avogadro di Quarequa e di Cerreto (1776-1856). 

Galvanic cells are named after the Italian doctor Luigi Galvani (1737-1798), who generated electricity using two metals. These cells are also called voltaic cells, after the Italian physicist Count Alessandro Volta (1745-1827), who built the first chemical batteries. 

One of Davy s first projects was to apply the newly invented electric battery to chemistry. The Italian physicist Alessandro Volta had demonstrated the first one only the previous year, 1800, and Davy immediately saw a use for them in his research. Soon after the first batteries were made, it was discovered that the electrical currents that they produced could be used to decompose chemical compounds. For example, if positively and negatively charged electrodes were inserted in water, oxygen was released at the negative electrode and hydrogen at the positive one. This phenomenon is called electrolysis. 

One day as the Italian physicist Enrico Fermi and George Uhlenbeck (who had come to the United States on a visit) were looking out a window overlooking Manhattan, Fermi remarked, You realize, George, that one small fission bomb could destroy most of what we see outside Fermi was soon to be doing some of the preliminary experimental work that preceded the American atomic bomb project. It was Fermi who produced the first controlled nuclear chain reaction. 

Methane has been used as a fossil fuel for thousands of years. The discovery of methane is attributed to the Italian physicist Alessandro Volta (1745-1827). Volta, known primarily... 

In 1811, the Italian physicist and lawyer Amadeo Avogadro (1776—1856) gave a brilliant explanation for Gay-Lussac s experimental results. Avogadro hypothesized that the fundamental particles of hydrogen and oxygen were not atoms but rather diatomic molecules, where the term diatomic indicates two... 

Carlo Marangoni, 1840-1925. Italian physicist, professor at a Lyceum in Pavia. 

Fermi was an Italian physicist who emigrated to the USA in 1939 and continued his studies there. Fermi produced a nuclear chain fission reaction by bombarding the isotope 23SU with neutrons. For his this achievement he won the 1938 Nobel. Prize in Physics. 

The fact that uranium is capable of undergoing a process known as fission was discovered as an indirect result of the use of neutrons as projectiles in the production of artificial radioactive isotopes. At the University of Rome, the Italian physicist Enrico Fermi bombarded many different elements with neutrons and thereby produced many new radioactive isotopes. The use of neutrons as projectiles has the distinct advantage that the collision of these uncharged particles with... 

Volt — SI-derived measurement unit of the electric -> potential difference or voltage. Symbol V (named in honor of the Italian physicist Alessandro - Volta (1745— 1827)). Definition lvolt is the potential difference between two points of a homogeneous, linear conductor of constant temperature, when a current of one ampere converts one watt of power. 

These questions are examples of Fermi problems, which involve large numbers (like the Avogadro constant) and give approximate answers. The Italian physicist, Enrico Fermi, liked to pose and solve these types of questions. 

By the end of 1925, there were essentially two versions of quantum mechanics Heisenberg s and Dirac s. The physical ideas were abstract and strange. The mathematics was foreign. Even the great Italian physicist Enrico Eermi found the ideas alien. What was needed was an application that would demonstrate the efficacy of the new quanmm mechanics. The American physicist... 

Avogadro s number N—The number of molecules present in one mole of whatever the compound is always equal to 6.0229 X 10. It was named for the Italian physicist Amedeo Avogadro. 

Italian physicist Enrico Eermi s (1901-1954) 1934 theory of beta decay used the neutrino hypothesis. (This theory, still used for approximate calculations, was only surpassed for more accurate calculations by theories developed in the 1970s.) But did neutrinos really exist In the 1930s, no experiments to detect them were possible. 

The first nuclear reactor was built during World War n as part of the Manhattan Project to build an atomic bomb. This reactor was constructed under the direction of Italian physicist Enrico Fermi (1901-1954) in a large room beneath the squash courts at the University of Chicago. Until the day on December 2,1942, when the Chicago reactor was first put into operation, scientists had relied entirely on mathematical calculations to determine the effectiveness of nuclear fission as an energy source thus, the scientists who constructed the first reactor were taking an extraordinary chance. 

Fermium was discovered in 1952, among the products formed during the first hydrogen bomb test at Eniwetok Atoll, Marshall Islands, in the Pacific Ocean. For security reasons, this discovery was not announced until 1955. Credit for the discovery of fermium goes to a group of University of California scientists under the direction of Albert Ghiorso (1915-). The element was named for Italian physicist Enrico Fermi (1901-1954). Fermi, who made many important scientific discoveries in his life, was a leader of the U.S. effort to build the world s first fission (atomic) bomb during World War II. 

Italian physicist Emilio Segre and his colleague Carlo Perrier discover technetium. 

At sea level, the atmosphere keeps the mercury in a barometer at an average height of 760 mm, which is 1 atmosphere. One millimeter of mercury is also called a torr, after Evangelista Torricelli, the Italian physicist who invented the barometer. Other units of pressure are listed in Table 1. 

What is a mole The mole, commonly abbreviated mol, is the SI base unit used to measure the amount of a substance. It is the number of representative particles, carbon atoms, in exactly 12 g of pure carbon-12. Through years of experimentation, it has been established that a mole of anything contains 6.022 136 7 X 10 representative particles. A representative particle is any kind of particle such as atoms, molecules, formula units, electrons, or ions. The number 6.022 136 7 X 10 is called Avogadro s number in honor of the Italian physicist and lawyer Amedeo Avogadro who, in 1811, determined the volume of one mole of a gas. In this book, Avogadro s number will be rounded to three significant figures—6.02 X 10. ... 

The voltaic cell is named for Alessandro Volta (1745-1827), the Italian physicist who is credited with its invention in 1800.
