Why does a chain reaction die out in small pieces of fissionable fuel but not in large pieces?
Because in small samples the probability of a neutron escaping the sample without inducing another fission is bigger. Actually, what matters is the mass of the sample, especially if this mass exceeds the critical mass. Thus, the chain reaction in a smaller sample with sufficiently higher density of fissionable material might not die out, while it dies out in a larger sample with albeit a sufficiently smaller density of fissionable material.

Why does Tchaikovsky's 1812 overture sound like Dvorak's carnival?
Both are large-scale orchestral pieces by romantic slavic composers. They are similar, but not very.
How does Travis explain the chain of cause and effect that he says would occur if a hunter accidentally killed even one mouse in a sound of thunder?
In "A Sound of Thunder," Travis explains that killing even one mouse could set off a catastrophic chain reaction in the ecosystem, altering the course of history. He emphasizes the concept of the "butterfly effect," where small actions can have disproportionately large consequences, leading to significant changes in the future. By illustrating this, Travis warns that even minor disruptions in the past can drastically reshape the present and future.
DMX what is the knecklace he wears made of?
DMX was often seen wearing a distinctive chain necklace made of large, bold links, typically in gold or silver. The necklace became part of his iconic style and represented his larger-than-life persona. While the exact material varied, it was often associated with hip-hop bling culture, emphasizing wealth and status. Additionally, he sometimes wore pieces that included religious symbols, reflecting his faith.
Can radium bombs be very destructive as it is million times radioactive than uranium?
The reason why an atomic bomb produces such a large explosion is that certain radioactive isotopes, such as U-235 or plutonium, can be made to undergo a chain reaction in which all the atoms will decay in a very short period of time (a small fraction of a second) releasing all the energy at once. Radium does not do that. However, if you had a substantial quantity of radium you could certainly use it to create radioactive contamination which could induce cancer in many people. That is known as a "dirty bomb".
What is a 17th-century solo vocal piece of music called?
FalseIt could be an aria, a cantata, a song.Searching on the word suite doesn't bring up anything vocal. In the 17th century a suite was a set of interrelated pieces for a solo instrument or an orchestra. Bach wrote suites for cello, for violin, for keyboard and for orchestra. A suite could also be a selection of pieces from a larger work, like Handel's Water Music Suite, made of pieces from a large set he wrote to be played as his King's barge floated down the Thames, or his Suite from the Music For The Royal Fireworks.
Neutrons released in a fission reaction can strike other nuclei and cause?
further fission reactions, leading to a chain reaction. This process releases more neutrons, producing a large amount of energy. Controlling the rate of the chain reaction is crucial for nuclear power generation and atomic weapons.
When many atoms are split in a chain reaction, a large explosion occurs This is an example of what type of energy conversion?
Your question has 2 parts:Assuming that 1 neutron starts the chain reaction, each generation takes 10ns, each fission produces 2.5 neutrons on average, and the chain reaction lasts 1us; the total fissions = 100000Nuclear energy to kinetic energy to heat energy.
What goes on when a nuclear chain reaction occurs?
A nuclear chain reaction occurs when a nucleus undergoes fission, releasing energy and more neutrons. These neutrons can then collide with other nuclei, causing them to also undergo fission and release additional neutrons. This process continues in a chain reaction, leading to the release of large amounts of energy.

What term describes the reaction process in a fission reaction?
another name for nuclear fission is: E=MC squared
What is the method that creates a large sample of DNA for testing from a small sample of DNA?
That would probably be polymerase chain reaction or PCR for short.
What is a large chain of islands?
An archipelago is a large chain of islands.
What are the two most commonly used fissionable substances?
The two most commonly used fissionable substances are uranium-235 and plutonium-239. Both of these materials undergo nuclear fission, releasing a large amount of energy that can be harnessed for power generation in nuclear reactors.
Why are radioactive substances useful in fission bombs?
Radioactive substances, such as uranium or plutonium, are used in fission bombs because they can undergo nuclear fission, releasing a large amount of energy in a chain reaction. This energy release is what creates the explosive power of the bomb.
Is there a way to split an atom?
YES in a process known as NUCLEAR FISSION a high speed neuron hits a large fissionable atom's nuclear, such as U-235 (235 is the mass number), it splits into 2 new, smaller atoms + 2 high speed neutrons + ENERGY (which may go on to cause further fissions causing a chain reaction: Good for Bombs, but bad for fission reactors, so some neutrons are slowed down by a moderator substance)
What type of reaction is cracking an example of?
Thermal Decomposition
