displacing liquid造句

• His power automatically displaces liquids and gases when he arrives.
• The weight of the displaced liquid can then be determined, and hence the relative density of the powder.
• When an object is immersed in a liquid, the liquid exerts an upward force, which is known as the buoyant force, that is proportional to the weight of the displaced liquid.
• If the object is more dense than the liquid then it begins to sink until the weight of the displaced liquid becomes equal to the object's weight; then it floats at that depth.
• The sum force acting on the object, then, is equal to the difference between the weight of the object ('down'force ) and the weight of displaced liquid ('up'force ).
• With the clarifications that for a sunken object the volume of displaced fluid is the volume of the object, and for a floating object on a liquid, the weight of the displaced liquid is the weight of the object.
• In other words, for an object floating on a liquid surface ( like a boat ) or floating submerged in a fluid ( like a submarine in water or dirigible in air ) the weight of the displaced liquid equals the weight of the object.
