What is the relationship between heat, temperature, thermal
energy within a system?

The thermal energy, orheat, of an object is obtained by adding up the kinetic energy of all the molecules within it.Temperature is the average kineticenergy of the molecules. 

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
