When a neutron hits water, it interacts with the atoms in the water molecules. It bounces around, and transfers energy, much like a billiard ball. As a result, it loses energy and is slowed down. This makes water an excellent moderator for nuclear power plants, causing the neutron to slow down to the thermal range where it can interact with subsequent uranium or plutonium atoms.
It is also possible that a water molecule (oxygen or hydrogen atom) can absorb the neutron, causing change in isotopic identity, fractioning the water molecule into radioactive oxygen and hydrogen.

What happens when water hits a sandcastle?
The sandcastle is swept away.
What happens when the gravity of a massive star is ablle to overcome neutron degeneration?
When the gravity of a neutron star overcomes the degeneracy pressure of the neutrons, the neutron star collapses into a black hole.
A neutron is an unstable particle outside a nucleus but to start nuclear fission requires the slowing down of a neutron. How is nuclear fusion carried out in the case of uranium?
The neutrons released from Uranium are fast neutrons. In a reactor they are slowed down by a moderator. The moderator could be water, heavy water, graphite, among others. When the neutron is slowed down, it is more likely to create fission.This is what happens with the U-235. The U-238 does not fission, but it does transmute through a series of neutron absorption and beta decay etc. into plutonium which does fission also.
In a nuclear fission reaction a freely moving neutron is introduced to a nuclear fuel such as uranium-235. What happens next?
a neutron is absorbed by an atom’s nucleus. (apex)
What is the purpose of californium?
The isotope 252Cf is a very strong neutron source; some applications are: - neutron's detectors for water and petroleum - control of nuclear fuel rods - treatment of some cancers by neutron irradiation - neutron radiography in industry - neutron activation analysis in mobile installations
What happens when water hits light?
the lightning vaporizes the water it hits and also charges the water with electricity (don't go swimming)
What happens when a neutron star runs out of fuel?
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
What happens if water hits terminal velocity?
Nothing "happens". This occurs all the time.
What happens to rain when it hits a raincoat?
It becomes regular water.
What happens when light hits water at an angle?
fills up it
What happens when water hits a sandcastle?
The sandcastle is swept away.
What happens when water hits polyester?
it explodes with you in it take that society
What happens to a neutron star that gives it the name pulsar?
the name pulsar is given to a neutron star that rotates
Does a neutron star have water?
No
What happens when water hits the ground?
You gotta clean the mess up:)
What happens when water vapor hits the cold atmosphere?
Fog.It makes fog.
What happens when the gravity of a massive star is ablle to overcome neutron degeneration?
When the gravity of a neutron star overcomes the degeneracy pressure of the neutrons, the neutron star collapses into a black hole.
