Gas is compressed aconstant pressure of 0.8atm from9.00L to 2.0L the process
To determine the process that the gas undergoes when it is compressed from 9.00L to 2.0L at a constant pressure of 0.8 atm, we can use the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.
In this case, we are given the constant pressure, so we can rearrange the equation as V1/T1 = V2/T2, where V1 and V2 are the initial and final volumes respectively, and T1 and T2 are the initial and final temperatures respectively.
Since the pressure is constant, we can assume that the temperature remains constant as well. Therefore, the process the gas undergoes when it is compressed is an isothermal process.
In an isothermal process, the temperature remains constant, so the equation V1/T1 = V2/T2 can be simplified to V1 = V2.
Therefore, the gas is compressed from 9.00L to 2.0L at a constant pressure of 0.8 atm through an isothermal process.
