Problem Details

Standard temperature and pressure (STP) are considered to be 273 K and 1.0 atm. Predict which of the following changes will cause the volume of the balloon to increase or decrease assuming that the temperature and the gas filling the balloon remain unchanged.

Balloon filled with helium at STP floats into the atmosphere where the pressure is 0.5 atm.

Balloon filled with helium at STP is submerged under water where the pressure if 1.25 atm.

Balloon filled with helium at STP floats into air where the pressure equals 1 atm.

Balloon filled with helium under water at 1.15 atm is released and floats to the surface, which is at STP.
