Volume measurement by displacement method | Density | Physics

Measuring cylinders help in finding volume of liquids, but what of bodies with irregular shapes? This video shows how to use the water displacement method to measure the volume of bodies. A measuring cylinder or overflow vessel is used to determine two volumes - the volume before a body is immersed and the volume with the body immersed. The reasoning is that the immersed body has displaced its own volume, so by calculating the difference in volume of water, we can find the volume of the body. Once we find the mass of the body, the density can then be calculated as mass/volume. Note that this method only works of the object whose volume is to be measured completely sinks in water.

  • @cindyandjoey

    To measure a floating object, could you do it like this?: First weigh the very light object on the scale. Say that it weighs 50g. Then you could use fine, almost weightless thread to tether the object to the bottom and pull it under water. The object will displace water. Let's say the level rises to 1600 ml, so amount displaced equals 1600 - 1000 = 600 ml, which is same as 600 cm^3. Now, you'd calculate density at 50g / 600 cm^3 = 0.08 g/cm^3. The answer should be a number less than 1 because water is 1 g/cm^3, and objects that float have a specific gravity less than water, so this seems correct.

    there is another way im not sure if it's correct, so basically as you said we weigh the light object let's say its 50g, you could then bring a heavy solid and measure it and see it's volume alone, then you put it above the light object for the light object to sink and you subtract the water and the heavy object which leaves you with the light object. (correct me if im wrong)

    if we tether a ball to the bottom of a tank and put the tank on scale and then we cut the thread, shouldn't the scale read higher momentarily until the ball reaches the surface or reaches its terminal velocity?
