## Ionization Energy: Potential, Methods For Determination

The ionization energy refers to the minimum amount of energy, usually expressed in units of kilojoules per mole (kJ / mol), which is required to produce the release of an electron located in an atom in the gas phase that is in its state fundamental. The gaseous state refers to the state in which it

## Ampère’s Law: Formula And Equations, Proof, Exercises

The Ampere ‘s law  states that the movement of the magnetic induction vector B is proportional to the intensity I of the current flowing through the same. In turn, the circulation of B  is the sum of all the products between the tangential component B ║  and the length of a small segment Δℓ of

## What Is The Voltage Divider? (with Examples)

The voltage divider or voltage divider consists of an association of resistors or impedances in series connected to a source. In this way, the voltage V supplied by the source -input voltage- is distributed proportionally in each element, according to Ohm’s law: V i = IZ i . Where V i is the voltage across

## Rutherford’s Atomic Model: History, Experiments, Postulates

The Rutherford atomic model is the description of the atom created by the British physicist Ernest Rutherford (1871-1937) discovered in 1911 when the atomic nucleus by the famous scattering experiments that take their name. The idea of ​​the atom (” indivisible ” in Greek) as the smallest component of matter , was an intellectual creation

## Isobaric Process: Formulas, Equations, Experiments, Exercises

In an isobaric process , the pressure P of a system is kept constant. The prefix “iso” comes from the Greek and is used to denote that something remains constant, while “baros”, also from the Greek, means weight. Isobaric processes are very typical both in closed containers and in open spaces, being easy to locate

## Newton’s Corpuscular Theory Of Light

The Theory corpuscular light Newton (1704)  proposes that the light material consists of particles that Isaac Newton called corpuscles. These particles are thrown in a straight line and at high speed by different sources of light (the Sun , a candle, etc.). In physics  light is defined as a part of the radiation field called

## What Is An Isothermal Process? (examples, Exercises)

The isothermal or isothermal process is a reversible thermodynamic process in which the temperature remains constant. In a gas, there are situations in which a change in the system does not produce variations in temperature, but does in physical characteristics. These changes are the phase changes, when the substance changes from solid to liquid, from

## Physical Adhesion: What It Consists Of And Examples

The physical adhesion is the binding between two or more surfaces of the same material or different material when contacted. It is produced by the Van der Waals force of attraction and by the electrostatic interactions that exist between molecules and atoms of materials. Van der Waals forces are present in all materials, are attractive,

## Transmittance: What It Is, Molecular Energy Diagram And Exercise

the transmittance Optical is the quotient between the emergent luminous intensity and the incident luminous intensity on a sample of translucent solution that has been illuminated with monochromatic light. The physical process of the passage of light through a sample is called light transmission  and thetransmittance it is a measure of light transmission. Transmittance is an

## Bernoulli’s Theorem: Equation, Applications And Solved Exercise

The Bernoulli theorem , which describes the behavior of a fluid in motion, was enunciated by the mathematical and physical Daniel Bernoulli in his Hydrodynamics . According to the principle, an ideal fluid (without friction or viscosity) that is circulating through a closed conduit, will have a constant energy in its path. The theorem can
