основное отличие жидкости от газа в общем случае это то, что газ сжимается, а жидкость нет. ну и соответственно плотность жидкости гораздо выше, а значит сила Архимеда действует сильнее. а так, жидкости и газы во многом похожи.

пипетка может создавать внутри себя избыточное или отрицательное давление газа и тем самым выталкивать или затягивать в себя жидкость, которая не сжимается.
