If i understand correctly from the answers above, i can't figure out how much water was displaced from the volume markings unless the object is fully submerged below the original water level surface, in my case below 4ml

The plate has volume of 1ml, it's length is smaller than the container wall length so it can fit inside. In the picture i drew the length in this way, that why the height of the plate exceeds the 1ml mark a little

Okay so the volume of the water that got displaced goes up to the 4.5ml mark even though only a small portion of the volume of the object got submerged

I submerge half of the piston and 0.5ml of water gets displaced on top, so where am I making a mistake?

When the object is half submerged, i am measuring that from the bottom of the object. And if I'm measuring from the surface of the water, then that surface is at 4.5 ml?

I feel like this is the dumbest question I've ever asked in my life, and honestly I'm sorry for taking anyone's time that's willing to answer. So I have a rectagular prism container that has 4ml of water and i submerged a metallic plate that has volume 1ml, just like the picture below. The...

Okay..i think i figured it out. Is the below correct?

Pressure increases. In my case pressure should decrease since i go the opossite way of the video. So in my senario: when the bubble was at the top the pressure at point 1 should be higher than the pressure at point 1 when the bubble is at the bottom

Omg you are right, this is a mistake in my drawing, i must re-upload it. The right position of the points are the ones in fig.C

Well according to the video when the bubble is at the short end, then any particular point is at a lower pressure rather than when the bubble is at the long side. So the higher system pressure is with the bubble at the top of the long side. I don't understand your question about the points 2...

Yes right J shaped

In my senario where we go from bubble at the top to bubble at the bottom if the air pressure doesn't change,meaning it stays Patm , then in fig. C the pressure at point 3 must be Patm since it's the point at the interface. Now point 3 is also at the same height with point 1 so these two points...

So in the video the claim that the pressure of the whole system increases, is wrong?

If the pressure of the air bubble stays the same then the pressure at the interface of the air and water will stay the same. If that's true then the pressure of the water doesn't change throughout the whole volume of water, it doesn't change at the point where the water touches the trapped air

That the pressure will remain Patm? But If you watch the video we see that the air pressure remains the same but the water pressure increases
