Overview
I'm working on a physics question and need support to help me learn.
A 1 litre balloon is filled with 1g of helium and heated up to a (3,2,1)
temperature of 298 K. The balloon is then released and the helium rushes out through the opening which has a radius of 40 mm.
1 mole helium = 4.003g
Air pressure = 103 kPa
Calculate the force of the helium leaving the balloon immediately after the balloon has been released.
