Question
05: A rigid vessel (A) is connected to a spherical elastic balloon (B). Both contain
air at the ambient temperature (25°C). The volume of vessel (A) is (0.1m³) and the
pressure is (300KPa). The initial diameter of the balloon is (0.5m) and the pressure
inside is (100kPa). The valve connecting (A) and (B) is now opened, and remains
open. It may be assumed that the pressure inside the balloon is directly
proportional to its diameter, and also that the final temperature of the air is
uniform throughout at (25°C). Determine the final pressure in the system and the
final volume of the balloon?
Ans. (136.7 KPa, 0.1672 m³)
