Classify each of the events based on whether the solubility of the gas will increase, decrease, or stay the same. Gas solubility increases                Gas solubility decreases                                            -                                            -                                            -                                            - Gas solubility does not change          Events The partial pressure of an anesthetic gas is increased. O2 in the blood of a person who is placed in a hyperbaric chamber. The pressure of a gas over a solvent is decreased. The temperature is decreased. Air in the blood of a diver breathing compressed air surfaces quickly.
