I have 130 liters of gas in a piston at a temperature of 250° C. If I cool the gas until the volume decreases to 85 liters, what will the temperature of the gas be?

For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with ph. if the solubility does change, pick the ph at which you'd expect the highest solubility. you'll find ksp data in the aleks data tab. compounds does solubility change with ph
