The idea 3) the "kinetic theory of matter".

Explanation:

The kinetic theory of matter states that matter comprises of huge amount of smaller particles which exhibit continuous movement due to which they have kinetic energy. The same concept is known by various other names such as Kinetic molecular theory of matter or kinetic theory of gases.

The Boyle's law gives the relation of pressure of ideal gas with its volume at constant temperature, whereas when the same relationship is explained in absolute temperature it is called Charles law. Archimedes' principle talks about the density of the liquid.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
