Describe a characteristic of a fissionable substance that is essential for a chain-reaction to sustain itself?
The fission process is sustained by neutrons. A neutron entering a nucleus and causing fission must be replaced in order to cause the next fission, and so on. So the fissionable substance must emit more neutrons when fission occurs, and enough of them so that despite some being absorbed by the moderator and some leaking from the reactor boundary, there is still enough to maintain the chain reaction. Uranium 235 emits on average about 2.5 neutrons per fission (you might say what is half a neutron, but this is explained by the fact that fissions have a range of possible results, with different numbers of neutrons emitted, and the average is 2.5).

Describe a characteristic of a fissionable substance that is essential for a chain reaction to sustain itself?
Firstly it must be able to capture neutrons which then have a high probability of causing its nuclei to undergo fission or splitting, and the fissions must produce enough further neutrons so that for every fission that occurs, another one will follow.
What is meant by a characteristic property of a substance?
A characteristic property of a substance is a unique and specific attribute that is inherent to that substance and helps to identify and distinguish it from others. These properties remain constant regardless of the amount or form of the substance and can be used to determine its identity.
What 2 conditions that density has to meet in order for it to be used to identify a mystery substance?
Density must be a characteristic property of the substance, meaning it is unique to that substance and doesn't change with the amount or shape of the sample. Additionally, the density value of the substance must be compared to known values to determine a match, so accurate measurement and comparison methods are essential.
What is one characteristic property of a substance?
i will give you three....melting point, boiling point, freezing point and one more is density
What is the characteristic property of a substance?
The characteristic property of a substance is a unique physical or chemical property that helps identify and distinguish that substance from others. These properties remain constant regardless of the amount or physical state of the substance. Examples include density, melting point, boiling point, and solubility.

A n blank property is a characteristic of a pure substance?
A physical property is a characteristic of a pure substance. Water is an example of a pure substance.
The characteristic of a substance that can be observed, without changing it into another substance, is called a?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance.
What is characteristic property of a substance?
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.
What is the characteristic of a substance that has no definite shape but definite volume?
The characteristic of a substance that has no definite shape but definite volume is called fluidity.
What is meant by a characteristic of a substance?
The Characteristic of a substance is the stuff you find after you masturbate, (if you get heaps it is a good option to go to the Doctor, you might have cancer.),
Is freezing a characteristic property?
Yes! Freezing (when a substance becomes solid) and melting points (when a substance becomes liquid) are characteristic properties.

Why is density a characteristic of a substance and volume and mass are not?
The volume and mass of a substance are independent of the substance itself, but depend upon how much there is of the substance The density of a substance is the relation between how much volume you have of a substance and how much mass that volume has (and vice-versa). It is independent of how much there is of the substance and is thus a characteristic of the substance.
Is boiling temperature a characteristic property?
Yes, boiling point is a characteristic property of matter. It is called a characteristic property because no matter how much of a pure substance you have, the boiling point should remain the same. Therefore, it is a characteristic property of pure substances.
When substance dissolved in another it is called?
This substance is the solute and this characteristic is called solubility.
