The mechanism of nuclear fission is best understood by noting that a massive nucleus behaves in many respects like a drop of liquid . According to this liquid drop model , the neutron absorbed by the 92U235 nucleus gives the nucleus extra energy (like heating a drop of water.

How does a valve cause a pressure drop in terms of the individual molecules in the liquid?
Soo
How does the shape of a liquid drop play a role in the evaporation rate?
The relatively great surface area of a liquid drop impacts the evaporation rate. The greater the surface area, the greater the rate of evaporation. the converse is also true.
What was Niels Bohr contribution to the atom?
The Bohr model of the atom, the theory that electrons travel in discrete orbits around the atom's nucleus.The shell model of the atom, where the chemical properties of an element are determined by the electrons in the outermost orbit.The liquid drop model of the atomic nucleus.Identified the isotope of uranium that was responsible for slow-neutron fissionThis answers came from wikipedia
What is saddle point in nuclear fission?
In the liquid drop model, excitation energy in a nucleus gives rides to modes of motion or oscillations. On a potential energy surface, the saddle point corresponds to the critical deformation of unstable equilibrium in the nucleus.
What happens if density of a solid substance is more than liquid?
It sinks in the liquid. A steel bolt has a density greater that that of water. Drop it in water, it sinks.
Why the temperature of the liquid decrease as the liquid evaporates?
Evaporation needs heat energy, the remaining liquid give up some heat energy to help the vapor form so the remaining liquid's temperature decreases.
What is the uses of the liquid dropper?
it is used to drop very small amount of liquid.
What is the use of a liquid dropper?
it is used to drop very small amount of liquid.
What are the function of pipette in laboratory?
three main functions: to accurately measure a volume of a liquid to accurately measure the amount of volume of a liquid required to add into a another liquid for a specific results to apply a a liquid to another liquid drop by drop for maximum efficiency
Does the density of a liquid affect its droplet shape?
A drop is a drop.Example? A drop of water is exactly like a drop of melted lead.Answer?No.
To change state from liquid to solid?
Drop the temperature.
Why we use collective model in nuclear physics?
When liquid drop and shell models fail to explain different phenomena like, electric quadrupole moment, magnetic dipole moment In addition to individual nucleons changing orbits to create excited states of the nucleus as described by the Shell Model, there are nuclear transitions that involve many (if not all) of the nucleons. Since these nucleons are acting together, their properties are called collective, and their transitions are described by a Collective Model of nuclear structure. High-mass nuclei have low-lying excited states that are described as vibrations or rotations of non spherical nuclei. Many of these collective properties are similar to those of a rotating or vibrating drop of liquid, and in its early development the Collective Model was called the Liquid-Drop Model. The first important application of the Liquid-Drop model was in the analysis of nuclear fission, in which a massive nucleus splits into two lower-mass fragments. The Liquid Drop Model calculates an energy barrier to fission as a sum of the repulsive Coulomb forces between the protons of the nucleus and the attractive surface tension of the skin of the "liquid drop" nucleus. If the barrier is low enough the nucleus might fission spontaneously. For higher barriers, it takes a nuclear reaction to induce fission. The figure above shows the energy levels of 238U. The quantum numbers, level spacings, and gamma ray transition probabilities identify these levels as rotational states of a non spherical nucleus. Nuclei showing collective properties are usually those with many valence nucleons, that is, those with proton or neutron numbers that are far from filled shells. As with the Shell Model, the Collective Model permits the calculation of spin-parity assignments and transition probabilities that are in good agreement with the measured properties of collective nuclei.
What is the volume of a drop of liquid?
1/15th of one millilitre.
How many microliters are in one drop?
The size of a drop depends on the surface tension of the liquid (and gravity). A standard medicinal drop 50 microlitres.
What will happen if you drop nuclear liquid?
Your question deals with nuclear fuel liquid. fluid fuels are not subjected to the structural stresses of solid fuels. If you drop liquid nuclear fuel, and you are not wearing protective gear, the Gaseous will sicken you and kill you.
A drop of liquid precipitation that is 2 mm in diameter is?
rain
Who was the model on Robert Palmer's pressure Drop?
The model on Pressure Drop is Geraldine Edwards. The picture was taken in late 1975 when she was eighteen years old.
