A closed container initially holds 50 monatomic Aparticles that have a combined energy of 480 units. After 100 monatomic B particles with a combined energy of 720 units are added to the container, the system is allowed to come to thermal equilibrium.

Part A

At equilibrium, how many energy units does each A particle have?

Part B

At equilibrium, how many energy units does each B particle have?

Solution

At equillibrium all the particles will have equal energy

this means that the total energy of the combined system

will be distributed evenly among all the subjects.

Total energy is, 480+720 = 1200 units

Total number of particles is, 50+100= 150

therefore, Energy of each A particle= energy of each B particle= 1200 unit/150 = 8 units.
