Inside a freely falling runaway elevator, your <em>apparent weight is zero,</em> and you have no way to tell that you're inside a freely falling elevator.
Your ACTUAL acceleration is the acceleration of gravity (9.8 m/s² down), but you have no way to test it or measure it.
All you can tell is that you feel weightless. Any experiment you can do inside the elevator shows you that Newton's laws of motion and gravity are all true, and that electromagnetic waves behave normally.
Since the door that leads to the room is opened, this gives room for particles to move into the next identical room and divided into octants. Now the amount of space that can be occupied becomes double, the number of basic states has increased by 404916
Evaporation is a surface phenomenon as the molecules of the surface gets sufficient energy to overcome the force of attraction which will help in converting to the vapor phase.
