On what does mass depend on?
For a given radioactive element, the critical mass required to initiate a self-sustaining chain reaction depends mainly on three aspects1) the purity of the element (elimination of unwanted isotopes or other elements)2) the shape of the mass3) the quantity of the massThese last two are practically the same, because both directly determine the neutron flux.the catalystthe polarity
What is caused when critical mass is reached?
a chain reaction
What is the critical mass of uranium-238?
Each isotope has a different critical mass. U235 is used because the mass needed to cause a reaction is smaller than almost all other isotopes. This critical mass is calculated as( 3.001 x 9.987 to the 11th power) Divided by the weight of one nuclei X 2.5675 (x 10 to the 24th power) divided by mass. This equals 7.702 X 10 to the 13th power divided by mass. You can tell by this calculation that critical mass for u235 is very low at about 1.3 kg. Best regards, Bruce
The most effective shape for achieving critical mass is a?
sphere
What is the most effective shape for achieving critical mass?
A sphere
How do you decide any drug molecule is an positive polarity or negative polarity in mass spectroscopy analysis?
depend on acidic and basic substance
What is the amount of fissionable material required to continue a reaction at a constant rate?
At less than critical mass, there are fewer "targets" for neutrons to strike, fission, and release more neutrons. As a result, the reaction dies out.
Why is polarity important?
The behavior and properties of chemical compounds depend also on the polarity of their molecules. Typical examples are the solubility or intermolecular associations.

When was Critical Mass - Threshold album - created?
Critical Mass - Threshold album - was created on 2002-09-02.
Does a moving object's distance depend on the object's mass and velocity?
The distance doesn't depend on the mass.
Ceiling fan is rotating clock wise or anticlock wise in India?
It would depend on the polarity of the motor.
Do nuclear reactors have critical mass?
We know that critical mass can be achieved in a nuclear reactor. If it could not, we'd not be able to get a chain reaction and generate heat to generate power. Reactors don't have critical mass when the control rods are in, but pull the rods, start the reactor up and away you go!
What is upper sub-critical limit for U235 mass?
The critical mass depends on the shape; I don't think there is an upper limit to that.For the case of a sphere, the critical mass for U-235 is 52 kg. The corresponding diameter of the sphere is 17 cm.
What is critical mass according to wolverine?
kingpen
