Expanding gas experiment

The process begins with gas under some pressure, , at temperature , confined to one half of a thermally isolated container (see the top part of the drawing at the beginning of this article). The gas occupies an initial volume , mechanically separated from the other part of the container, which has a volume , and is under near zero pressure. The tap (solid line) between the two halves of the container is then suddenly opened, and the gas expands to fill the entire container, which has a … WebThis expansion of the balloon is due to the expansion of the air molecules present in the flask. However, the conversion of liquid water into water vapors is also responsible for the inflation of the balloon. ... Due to which the volume of the gas increases and hence gas expands. In the above experiment, on heating the kinetic energy of air ...
