Answer:
Carbon-14 has a half-life of 5,730 years. Taking one atom of 14C, this will either have decayed after 5,730 years, or it will not. But if this experiment is repeated again and again, it will be seen that the atom decays within the half life 50% of the time.
Explanation:
Heat in Physics is an energy that is in a process of transfer between a system and its surroundings other than the transfer of matter. In Thermodynamics, a science that deals with the study of heat and temperature and their relationship to energy and work, finer details of the process is unpredictable. Heat flows from a hotter to a colder body when there is a physical pathway. This pathway is suitable and can be direct such as radiation and conduction. It can also be indirect as in convective circulation.
