When is thermal equilibrium achieved between two objects?

Answer 1

No, it would be nonsense. If that was true, a single drop of water could drop the oven's temperature from 100 to 0.

Temperature isn't a measurement of energy. It's merely an average of kinetic energies of particles the body is made of.

Answer 2

No. The quantity of heat that flows out of one is equal to the quantity that flows into

the other one, but the changes in temperature don't have to be equal.

By the same analogous token, if you were to dip a glass of water out of an Olympic

swimming pool, the level of water in the glass might rise 8 inches, but the level in the

pool would not drop by too much.

Answer 3

Depends on what you mean by 'flow'.

For all objects above absolute zero (-273 deg C) the atoms within a material vibrate.

Therefore at the interface where two objects meet, some of the energy from the atoms in the first object will be transferred (ie 'flow') to the kinetic energy of the atoms of the second object.

However, at the same time, some of the energy from the atoms in the second object will be transferred (ie 'flow') to the kinetic energy of the atoms of the first object.

For two objects whose internal energies are equal, the precise energy transfer in these two processes will be equal and so the net heat flow will be zero.

Answer 4

when the temperature of both object (near or touching with each other) is different.

the larger the temperature difference, the more thermal energy is transfered; from the object with higher temperature to the one with lower temperature.

Answer 5

No. If the two objects are at temperature equilibrium, there is no heat difference between them and thus no net flow.

Answer 6

When both objects have the same temperature. ∞

Answer 7

That's when they have the same temperature, which you can measure with a thermometer.

Answer 8

Yes

Answer 9

the answer is when they have the same tepmture
