the heat content of a material
the average kinetic energy of particles in a material
the pressure exerted on a material
the acceleration due to gravity exerted on a material

the heat content of a material

Temperature measures the heat content of a material.

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.

It might. it might because if you think about if they discovered if we came from (lets say something funny like aliens) and thy found cells that matched and they would have t do more research about it but would most probably change their theory.
