Density and Buoyancy You read about heat in Chapter 4 In this chapter you'll learn a little more about heat and learn about two new concepts— density and buoyancy Take a guess at what these terms mean You may have heard them before Here are a couple of hints Density helps explain why a piece of steel sinks in water and a beach ball
Filtration Filtration is the process by which solid materials are removed from a fluid mixture either a gas or liquid mixture One of the most familiar kinds of filtration is that which students of chemistry encounter in their early laboratory experiences In these experiences suspensions of a solid precipitate in water are passed through filter paper supported in a glass funnel

The invention relates to the field of extracting helium from natural gas and can be used in hydrogen storage and transportation of hydrogen Currently the main method of sorption (allocation) of helium from natural gas is a cryogenic method which is the condensation of the hydrocarbon fractions
Helium balloons work by the same law of buoyancy In this case the helium balloon that you hold by a string is floating in a pool of air (when you stand underwater at the bottom of a swimming pool you are standing in a pool of water maybe 10 feet deep -- when you stand in an open field you are standing at the bottom of a pool of air that is many miles deep)

Aha well if it ain't our friend fluid dynamics The dang real world makes it really easy to forget that oxygen is fluidic just in a tad more gaseous state than water It ends up helium is lighter than oxygen and a balloon's lift is a result of the molecules fighting to balance themselves You see the same thing with a flotation device on
This then is the story of submarine operations in U S waters in 1918—a half hearted effort of short duration started late in the day—but which destroyed 100 ships totalling 200 000 tons most of them close to our shores No one could doubt but that in the event of another war submarines would be used again and in more vigorous fashion
The reason why things float in water applies to air as well so let's start by understanding water flotation Let's say that you take a plastic 1-liter soda bottle empty out the soft drink it contains put the cap back on it (so you have a sealed bottle full of air) tie a string around it like you would a balloon and dive down to the bottom of the deep end of a swimming pool with it

Density What we are actually comparing is the mass per unit volume that is the density In order to determine these densities we might weigh a cubic centimeter of each syrup If the heavy syrup weighed 1 30 g and the light 1 15 g we could describe the density of heavy syrup as 1 30 g cm –3 and that of light syrup as 1 15 g cm –3 (Note that the negative exponent in the units cubic

When I asked Fountaine Pajot's Laurent Fabre if the new Astrea 42 was replacing Fountaine Pajot's earlier Helia 44 his response was a firm "Non!"The reason he said is the Astrea isn't just a shortened or tweaked design but rather an all-new design for this LOA that borrows a number of features from the French builder's award-winning Saona 47
