Abstract
Measurements of the expansion behavior of single bubbles of an insoluble gas by monitoring the pressure change in a gas space at the top of a closed column show that the same expansion law applies both to the bubble and the gas space, but the correct expansion law cannot be deduced from pressure measurements alone. Results from a semi‐quantitative heat transfer experiment indicate that isothermal expansion should be assumed.
