Extensive properties, such as mass and volume, depend on the amount of matter being measured.Intensive properties, such as density and color, do not depend on the amount of the substance present.Physical properties<span> can be measured without changing a substance's chemical identity.</span>
Carbon-14 and Uranium-238 have something we call a half live, which is basically a known time period for it to change half of its C-14 or U-238 radioactively decay. Since we know how long that is 5730 years for Carbon-14 for half a sample to deteriorate, than we can figure out how old it is.
When the work is being done, it is likely that there is an energy being enforced and when the energy is being enforced, it is likely that the energy present is being transferred in order for the work to be able to be able to be exterted upon
