it means delta T=0 then delta Einternal=0phyzguy said:What is temperature? What does it mean to be in thermal equilibrium?
Any Help said:it means delta T=0 then delta Einternal=0
Temperature is a measurement of how heat or cold an object is. It reflects the delta internal energy where the change in temprature will cause a change in internal energy.phyzguy said:You didn't answer my question about what is temperature.
okay, but also its proportional to massphyzguy said:From the Wikipedia article on temperature:
"The kinetic theory offers a valuable but limited account of the behavior of the materials of macroscopic bodies, especially of fluids. It indicates the absolute temperature as proportional to the average kinetic energy of the random microscopic motions of those of their constituent microscopic particles, such as electrons, atoms, and molecules, that move freely within the material."

ah okay I got your point thanksphyzguy said:No! It's not! Temperature is proportional to the average kinetic energy of the constituent particles. So if two gases have equal temperatures, they have equal average kinetic energies. So the heavier particles are moving slower.
In thermodynamics, thermal equilibrium refers to a state in which two or more systems have reached the same temperature and there is no net transfer of heat between them.
Monatomic ideal gases in thermal equilibrium behave according to the Ideal Gas Law, which states that the pressure, volume, and temperature of the gas are all directly proportional to each other.
In thermal equilibrium, the kinetic energy of gas molecules is equalized between the two gases, meaning that they have the same average speed and therefore the same kinetic energy.
The number of particles does not affect thermal equilibrium, as long as the gases are in the same temperature and pressure. This is because thermal equilibrium is based on the energy and not the number of particles.
Thermal equilibrium can be disrupted by changes in temperature or pressure, as well as the addition or removal of energy through heat transfer. Changes in volume or the addition of new particles can also disrupt thermal equilibrium.
