1. The problem statement, all variables and given/known data An expandable cylinder has its top connected to a spring with force constant 2.00 103 N/m. (See Fig. P10.58.) The cylinder is filled with 4.00 L of gas with the spring relaxed at a pressure of 1.00 atm and a temperature of 20.0°C. (a) If the lid has a cross-sectional area of 0.0100 m2 and negligible mass, how high will the lid rise when the temperature is raised to T = 230°C? (b) What is the pressure of the gas at 230°C? 2. Relevant equations PV=nRT PiVi/Ti= PfVf/Tf 3. The attempt at a solution Ok I did Pf= Pinitial+ k(spring constant)(h)/Area Also Vf= Vi + h(Area) Then I plugged these into the PiVi/Ti= PfVf/Tf and its not the right answer What am I doing wrong?
