Assume that you have a cylinder with a movable piston. What would happen to the gas pressure inside the cylinder if you do the following?
Part A:Decrease the volume to one-fourth the original volume while holding the temperature constant.Express your answer in terms of the variable P initial.
Part B:Reduce the Kelvin temperature to half its original value while holding the volume constant.Express your answer in terms of the variable P initial.
Part C:Reduce the amount of gas to half while keeping the volume and temperature constant.Express your answer in terms of the variable P initial.
