Question

temperature and thermal energy(heat)

Answer 1

so i know that temperature is the total kinetic energy off all the particles in a substance

and heat is the transfer of this energy from one to the next due to difference in temperature

but my notes say that thermal energy is also the total kinetic energy of the entities of a substance? is that right?

Answer 2

Yes, Thermal Energy is the total potential and kinetic energy of a substance. The quantity of thermal energy of a substance depends on how fast its entities (such as atoms, ions, or molecules) are moving. Temperature is a measure of the average kinetic energy of the entities in a substance.

Answer 3

is there a difference pertaining to the kinetic energies of these two?

Answer 4

Thermal enery is to be taken account under kinetic energy, because when particles move, there is always friction against their motion and such friction causes release of heat, the reason why heat energy iproportion to kinetic enegy.

Answer 5

oh and in a calorimeter, it doesnt matter what kind of setup as ong as there is a system and surroundings right?

Answer 6

that transfers heat energy from one to the other?

Answer 7

In a calorimeter, that consists in a polysterene cup with a double-insulating material, the heat released from a reaction is maintained in the system, because almost 100% of the eneries released are kept inside it , giving the experimenter a good accuracy in measuring temperature.
