The half-life of a radioactive material is a constant property that does not depend on the amount of material present. It is defined as the time required for half of the radioactive atoms in a sample to decay, and this rate is determined by the material's inherent decay characteristics. Therefore, increasing the amount of material does not change its half-life; it only affects the total time it takes for a larger quantity to decay to half its original amount.
No, the half-life of a material is a constant characteristic of that material and does not change based on the amount of parent material present. The half-life remains the same regardless of the quantity of the substance being measured.
The length of a pencil is an extensive property because it depends on the amount of material present (the length increases as more material is added).
No, the half-life of a material is a constant characteristic specific to that material and is independent of the amount present. The half-life is defined as the time required for half of the material to decay, and this rate remains the same regardless of the quantity. However, the total time for a given amount to decay completely will vary with the initial quantity, but the half-life itself does not change.
Solute
No, the volume of the material increases when a solution is diluted because you are adding more solvent to decrease the concentration of the solute. Diluting a solution does not change the total amount of material present, but it does change the volume in which that material is dispersed.
No, the half-life of a material is a constant characteristic of that material and does not change based on the amount of parent material present. The half-life remains the same regardless of the quantity of the substance being measured.
The length of a pencil is an extensive property because it depends on the amount of material present (the length increases as more material is added).
Yes, potential energy is an extensive property as it depends on the amount of material or mass present. This means that the total potential energy of a system increases with the quantity of material or objects in that system.
increases
Solute
The amount of gas present in the bag will increase as the dry ice sublimates.
No, density is an intrinsic property of a material and does not depend on the amount present. Density is defined as mass per unit volume, so it remains constant regardless of the quantity of the material.
an independent variable will not change with the amount of matter present. Think of it as being independent of the amount of material that is there
Of course, "halflife" is not the correct term to use in this context, so I am supposing that you are asking how long as in "how many years of use" or "how many rounds fired" can you expect an M16 to function. This is also called "service life". The answer depends entirely on how the machine is treated. If it is properly cleaned and has minor parts replaced as they wear and break, the rifle will last for many years and/or many tens of thousands of rounds. You can research the endurance testing that the US Army has employed to determine the tolerance to hard use. "Halflife" refers to radioactive material and is the amount of time required for half of the material to decay.
As more matter is packed into the same amount of space, the material's density increases. Density is defined as mass per unit volume, so as the amount of matter in a given volume increases, the density will also increase.
Mass is an Extensive phisical property
There is no change; specific heat is an intensive property of a material, independent of the amount.
