Question:

A cylinder fitted with a piston contains liquid methanol at 20C, 100 kPa and volume 10 L. The piston is moved, compressing the methanol to 20 MPa at constant temperature. Calculate the work required for this process. The isothermal compressibility of liquid methanol at 20C is 1220 (m) 2/N.
