Which statement best describes heat and thermal energy? They are different words for the same thing.
They represent different concepts.
Heat is what happens when thermal energy stops moving between substances.
Thermal energy is what happens when heat moves between substances.

Thermal energy is what happens when heat moves between substances.

Thermal energy usually refers to the temperature of an object which indicates the energy it has

Temperature is used as a guide to the level of thermal energy from objects

While heat is the transfer of thermal energy

Heat moves when there is a difference in temperature

The amount of heat is influenced by the mass of the object and the difference in temperature

Can be formulated  :

Q = m.c.ΔT

Q: heat received or removed by an object (J)

m: object mass (kg)

c: heat type substance (J / kg⁰C)

ΔT: temperature change (⁰C)

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