## Homework Statement

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?

## Homework Equations

PV=nRT

PiVi/Ti= PfVf/Tf

## 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?
