prepare the diver which is a test tube‚ fill the test tube about 50-60% with water‚ place the diver inside the bottle the diver should float near the water surface then secure the cap on the bottle. When the container is squeezed‚ the diver should sink to the bottom of the container. Release the bottle slowly‚ the diver should come up in reverse order. The Cartesian diver shows that air is compressible and water is incompressible. When the container is squeeze‚ the pressure from squeeze is distributed

each object and how it affects whether the object will sink or float. Lab Setup 1. Click over to the Buoyancy Playground and begin the lab. 2. There are 5 different fluids to choose from in the lab and five different types of materials. (Styrofoam‚ wood‚ ice‚ brick and aluminum) 3. Use the table supplied to organize your work. Lab Procedure: Part 1 1. In each of the scenarios below‚ determine first‚ by predicting‚ whether the object will sink or float. Use a mass of 4.5 kg. 2. Test each object

might need two people to hook it onto the mounting hardware. The mounting hardware is the popular stainless steel Quick Lock Sink Mount. You just "twist it off" to remove and "twist it on" to mount. All Insinkerator disposals use this mounting hardware. Thus‚ when you replace an existing Insinkerator unit‚ you save time and effort. That is‚ if you use back the existing sink flange and mounting hardware. We found the following items are not included in the package: (1) Power cord If you replace

minerals from diluted water deposit on certain surfaces of your home. It can be easily found around the sinks‚ taps or shower. The best way to remove the limescale is to prevent it‚ because it becomes much harder to remove it once it starts to build up. The fact that it affects our kitchen sink can be very annoying and frustrating‚ so here is what you can do in order to remove limescale from your kitchen sink. Scrab it with limescale removal The most common way in which you can remove the limescale is

King of Syracuse’s crown with silver. Density is the compactness of a substance. The new concept of density he discovered was used to expose the fraud. The purpose of this experiment is to make the heaviest floating film container without having it sink. The density of water is 1‚ so in order to keep the film container from sinking‚ the density of the sand-filled film container must be less than 1. The equation for density is D=m/V‚ where m is mass and v is volume. To find the volume of the film

tightly. 3. Squeeze the bottle‚ but not too tightly. Notice how the dropper sinks to the bottom of the bottle‚ but when you release your grip‚ the dropper floats back to the top. Why is that? There are certain forces that allow the diver to sink and float. They are: • States of Matter • Buoyant

understood for some time now. The basics of buoyancy involve the relationship between the weight of the object in question‚ in this case a boat‚ and the weight of the water it displaces. If the object weighs more than the water it displaces‚ it is going to sink to the bottom. This object is negatively buoyant. If the weight of the object is the same as the weight of the water it displaces‚ it is going to hover suspended in the water. This is called neutral buoyancy. Finally‚ if the weight of the object is
