Explain why it is not possible to use the ideal gas law only to determine if the pressure changed in this process. © Physics Education Research Group, University of Maryland, College Park, Fall 2008 "#$%& !"#$%&’( *+,,-.%/00"%/ &1 &2/’( 3’0/0 3%456+7& 2. A long pin is used to hold the piston in place as shown in the diagram. The cylinder is then placed into boiling water (the valve is kept closed/shut the whole time). A. Does the temperature of the gas increase, decrease, or remain the same? B. Sketch this process in the PV diagram at right. C. Explain why for this particular situation, it is not possible to determine the pressure of the gas as you did on page 1 of the tutorial (i.e., by considering a free-body diagram of the piston).
