Critical mass depends on the number of people or resources needed to create a self-sustaining reaction or movement. For example, in social movements, critical mass is the point at which there are enough supporters to effect change. In nuclear reactions, critical mass is the minimum amount of fissionable material needed to sustain a chain reaction.

Does critical mass depend on polarity?
No, critical mass does not depend on polarity. Critical mass is simply the amount of fissile material needed to sustain a nuclear chain reaction. Polarity, which is a property of molecules, does not play a role in determining critical mass.
What is the amount of radioactive material needed to sustain a chain reaction in order to provide useful energy called?
The critical mass.
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
What is the minimum mass of a fissionable isotope in which a nuclear chain reaction can occur?
The minimum mass of a fissionable isotope needed for a nuclear chain reaction is known as the critical mass. This mass varies depending on the specific isotope and the conditions of the reaction, but for uranium-235, which is commonly used in nuclear reactors, the critical mass is around 15-25 kilograms. To sustain a chain reaction, the mass of the fissionable material must exceed this critical mass.
What is caused when critical mass is reached?
When critical mass is reached, a self-sustaining chain reaction occurs, leading to a nuclear explosion in the case of nuclear fission. In social contexts, critical mass refers to the point at which a movement or idea gains enough momentum to be self-sustaining and bring about significant change.
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.
Does critical mass depend on polarity?
No, critical mass does not depend on polarity. Critical mass is simply the amount of fissile material needed to sustain a nuclear chain reaction. Polarity, which is a property of molecules, does not play a role in determining critical mass.
When was Critical Mass - Catholic rock - created?
Critical Mass - Catholic rock - was created in 1996.
What is the amount of fissionable material required to continue a reaction at a constant rate?
The amount of fissionable material required to sustain a nuclear reaction at a constant rate is determined by the material's critical mass. The critical mass is the minimum amount of fissionable material needed to sustain a chain reaction, and it varies depending on the material and the reactor design. By controlling factors such as neutron moderation and absorption, reactor operators can adjust the critical mass to maintain a steady reaction rate.
When was Critical Mass - Threshold album - created?
Critical Mass - Threshold album - was created on 2002-09-02.
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 not a factor in determining critical mass is?
The color of the bicycles is not a factor in determining critical mass. Critical mass refers to the minimum number of participants needed for a collective action to be effective, typically in the context of a protest or demonstration involving cyclists. The factors that do influence critical mass include the number of participants, their level of commitment, and the visibility of the event.
What is the amount of radioactive material needed to sustain a chain reaction in order to provide useful energy called?
The critical mass.
What is Lack of critical mass?
Lack of critical mass refers to a situation where a certain level of participation, support, or resources is needed for a particular activity or initiative to be successful or sustainable. Without this critical mass, the effort may not be able to achieve its intended outcomes or impact.
