Solve the problem. The data in the table was obtained for a gas at constant temperature. The gas was contained in a syringe and the volume of the gas was varied by squeezing the syringe. The pressure (in atmospheres) of the gas was measured for various volumes (in cm3) of the gas.
Let P be the pressure (in atm) of the gas when the volume is V (in cm3). Find an equation of a model to describe the data. Use the point (8, 1.17) to find the constant of variation. In a sentence that uses the phrase "varies directly" or "varies inversely", describe how the volume and pressure of the gas are related. Use the model you found to estimate the volume of the gas if the pressure is 0.80 atm.
