Solution:
Carbon dating is only useful for relatively recent objects, it is more often used to date man-made. Fossils are dated using radiometric data from heavier elements like Uranium and by analysis of the strata in which they appear. Radiometric data is considered valid if several readings on the same object fall within a reasonable margin of error.
We use carbon dating because, Carbon dating only works on things that were once alive -- plant fossils, animal & human remains, etc.It works because when organisms are alive, they accumulate carbon during biological processes. Some of the carbon is carbon 14, a radioactive element whose ratio to normal carbon in living things is constant. When the organism dies, it stops accumulating carbon, and the carbon 14 decays radioactively with a half-life of about 5,700 years. It means 5,700 years after anything dies, there will be half as much carbon 14 as there was when it was alive. Measuring the ratio of carbon 14 to normal carbon in a fossil can give a pretty accurate measure of how long ago an organism died.

B) How does convection oven cook food?
Explanation:
Chemistry is a science that primarily studies matter, the properties and reason for their combination.
Chemistry will not be able to answer the question of how convection oven cook food. This govern by physics. In this problem, we are not seeking to understand the nature of the matter in the context or how cooking changes the matter, all we desire is how heat is transferred to cook food.
Physics will provide a more succinct answer to this problem.
