    Chinese

    20181010&ensp·&enspThe pressuregradient force is the force which results when there is a difference in pressure across a surface. In general, a pressure is a force per unit area, across a surface. A difference in pressure across a surface then implies a difference in force, which can result in an acceleration according to Newton's second law of motion, if

    2015815&ensp·&enspBecause if intermolecular forces are low, at a given temperature it is more likely for a random molecule to have enough energy escape those forces (the tail of the maxwellboltzmann distribution) and become a free particle, like those in a gas.
