In an oedometer test, the void ratio of a clay sample changed from 1.62 to 1.41 as the vertical effective stress imposed on the sample was increased from 100 kPa to 200 kPa. Later on, the vertical effective stress on the sample was decreased by 100 kPa, resulting in an increase in void ratio to 1.44. Calculate the coefficient of volume compressibility (mv), the compression index (Cc), and the expansion index (Ce).
