A barometer accidentally contains 6.5 inches of water on top of the mercury column (so there is also water vapor instead of a vacuum at the top of the barometer). On a day when the temperature is \(70^{\circ} \mathrm{F}\), the mercury column height is 28.35 inches (corrected for thermal expansion). Determine the barometric pressure in psia. If the ambient temperature increased to \(85^{\circ} \mathrm{F}\) and the barometric pressure did not change, would the mercury column be longer, be shorter, or remain the same length? Justify your answer.
