Two columns of different liquids have the same height and cross-sectional area. Liquid X is denser than liquid Y. Which statement explains why the pressure due to liquid X at the base is greater?
Column X has smaller mass, so its weight per unit area is greater.
Column X has greater mass, so its weight per unit area is smaller.
Column X has smaller mass, so its weight per unit area is smaller.
Column X has greater mass, so its weight per unit area is greater.
