问题1:气体的压强是由于气体重力引起的吗?释疑:我们知道,压强是由于压力作用引起的,固体、液体的压强,一般说来,它们的压力来源于它们所受的重力,依此类推,大气压强就是由于地面上方大气层空气重力压在地面上形成的,能不能依此类推得出,气体压强就是由于气体重力引起的结论呢?显然不能,例如打足了气的足球内气体压强大于外界大气压强,然而足球内少量气体的重力却很小,可以忽略不计,可 Question 1: Is the gas pressure caused by the gas gravity? Interpretation: We know that the pressure is due to the pressure, the pressure of the solid and the liquid. Generally speaking, the pressure comes from the gravity they are subjected to. Based on this, Analogy, the atmospheric pressure is due to the air above the ground gravity air pressure formed on the ground, can be deduced by analogy, the gas pressure is due to the conclusion caused by gas gravity? Clearly not, for example, playing football gas pressure Greater than the outside world pressure, however, a small amount of gas in the ball of gravity is small, can be neglected, but
