Would get displaced, right? In that case, we'll have a smaller value. Is floating or sinking, right? I mean, think about it, if our object were to float like this, let's say somewhat this way, then because only a smallĪmount of object is submerged, only a small amount of water Now, how do we do this? How do we figure that out? Well, first of all that value depends on whether our object Not the mass of the entire water, but how much water got displaced, that's what we need to figure out. One gram per cm cube, and we need to calculate what the mass of the displaced water is. So anyways, density of water that is given to us as So density, now instead of writing the word density, I usually like to use this symbol rho, which is just to save space.

So we know the volume that has given us 40 cm cubed, we are also given the density of water. The object is 30 grams, we are given the volume of the object. So what is given? We are given the mass of the object. And we're asked to calculate what the mass of that displeased water is. You submerged something, the level of water rises because the water gets displaced. Raises the level of water, and that's why we knew when That liquid that comes, moves over here and Object inside any liquid, or any gas for that matter, then as that object gets submerged, some of that liquid has to move away to make space for that object, right? So that liquid that goes away is what we call the displaced What does that mean? Well, whenever you drop any So let's say we haveĪ container with water and it's given that we take this stone and we'd drop it in water. We know it's mass and we know it's volume, we'll write that down in a while, but it's dropped in water. So let's say here is our object, imagine it's a stone. So we're given an object of mass 30 grams.

Let's first try and draw the situation and then see how to solve it. Calculate the mass of displaced water, given the density of water An object of mass 30 gramsĪnd volume 40 cm cube is dropped in water. Solve a couple of problems to see how to calculate the amount of liquid displaced when something is floating on top of it and when something sinks into it.
