3 particles with a unit energy of 5.

Find the total # of macrostates.

Find the # of microstates for each macrostate.

Solutions

Expert Solution

The total energy of 5 units is distributed among 3 particles

so, the macrostates will be like:

(0,0,5) or (1,2,2) or (3,2,0) or (4,1,0)

therefore, the number of macrostates is 4.

If the particles are INDISTINGUISHABLE, for the macrostate (0,0,5) there is only 1 microstate

(0,0,5) = (0,5,0) = (5,0,0)

number of microstates for (1,2,2) is 3

[they are (2,1,2), (1,2,2) and (2,2,1)]

number of microstates for (3,2,0) is 6 with the states being (3,2,0) , ( 0,2,3) , (3,0,2) , (2,0,3), (2,3,0) and (0,3,2).

number of microstates for (4,1,0) is 6 with the states being (4,1,0) , (4,0,1) , (0,1,4) , (0,4,1), (1,4,0) and (1,0,4).

What physically causes energy to make subatomic particles move? I know energy causes particles to move "kinetic energy" and the measure of kinetic energy is particles jiggling and colliding with one another giving temperature. But what physically causes "energy" to be able to move the partices? Which gives heat.
