Thermal equilibrium of an ideal gas in a free-floating box

American Journal of Physics AIP Publishing 89:8 (2021) 789-792

Authors:

Scott Tremaine, Bence Kocsis, Abraham Loeb

Abstract:

The equilibrium and fluctuations of an ideal gas in a rigid container are studied by every student of statistical mechanics. Here, we examine the less well-known case when the box is floating freely; in particular, we determine the fluctuations of the box in velocity and position due to interactions with the gas it contains. This system is a toy model for the fluctuations in velocity and position of a black hole surrounded by stars at the center of a galaxy. These fluctuations may be observable in nearby galaxies.
