UTF-8Transfer of Kinetic Energy between hot and cold particles of same mass What happens when "Heat" flows from hot molecules to cold molecules?
The molecules in this simulation are colored according to how much kinetic energy they have. Molecules
with a lot of kinetic energy ones are red -- we call them hot. Cold ones are white.
Between the hot and cold molecules is a rigid barrier made of heavy atoms that bond tightly to
each other. Can Heat "flow" from the hot to the cold molecules? How does this happen?
Run the simulation to see. Watch the graph which shows the average Kinetic Energy/particle for the
gas molecules on the right, the gas molecules on the left, and the atoms in the barrier.
Does the average KE of the molecules on the right and left change? What eventually happens to the KEs?
What do we mean when we say the molecules on the right and left eventually reach "Thermal equilibrium"?
Would you expect this process to reverse itself and for "heat to flow" from the left BACK to the right side?
