Bob puts several pieces of dry ice inside an empty water bottle and covers the spout with a balloon. After 5 minutes the balloon is inflated. Elaborate on what process is occurring.
A) The expanding gas is exerting pressure and doing work on the walls of the balloon causing it to inflate.
B) Quick moving molecules of the developing balloon use the gas to create work and put energy into the system.
C) The slow moving particles of the gas are transferring entropy to the expanding balloon causing it to weaken.
D) Energy is converted to enthalpy as the compression dry ice particles occurs and the gas collides with other gas particles.
