Density and Buoyancy 21

Archimedes The Greek thinker of Syracuse whose principle gives the size of the buoyant force.
Balanced Describes two forces that cancel out, as weight and upthrust do on a floating object.
Buoyancy The upward force that a fluid puts on an object resting in it.
Buoyant Able to float; also the name of the upward force from a fluid.
Depth Distance below the surface; the pressure in a fluid grows with it.
Displace To push fluid out of the way and take its place.
Equal The same in amount, as a floating object's weight and the weight of fluid it displaces.
Eureka A cry of discovery that tradition credits to Archimedes.

Diver A person who wears weights underwater to cancel the lift of a diving suit.
Helium The usual lifting gas in a blimp, chosen over hydrogen, which burns.
Hot air balloon An aircraft that rises because the heated air inside is less dense than the air outside.

Hydrogen The lightest element, a gas that lifted early airships.
Iceberg A huge frozen mass, broken off a glacier or an ice shelf, adrift with much of it under water.
Keel The long piece along the very bottom of a boat that helps keep it steady.
Life jacket A vest that keeps its wearer afloat with head and mouth above the water.
Load line The mark on a hull that shows how deep a ship may legally sit in the water.
Pontoon An airtight hollow float that holds up a boat or a floating pier.
Raft A flat floating platform with no hull.
Ship A large watercraft; its weight matches the weight of the water it pushes aside.
Submarine A watercraft that works underwater, diving by changing the water in its tanks.
Swim bladder A gas-filled organ with which a bony fish controls its buoyancy.
Tank A compartment that holds water as ballast in a ship or submarine.
Waterline The level the sea reaches on the side of a floating ship.

Dense and Light Materials 20

Aerogel A man-made solid of extremely low density, with gas where a gel's liquid was.
Air The mix of gases around Earth, about 800 times less dense than water.
Aluminum A light metal, about one third as dense as steel.
Balsa A very soft wood, strong for its low density.
Brine Water with a high concentration of salt.
Cork A light, buoyant bark material used for bottle stoppers.
Ebony A dark hardwood; a few kinds are so dense that they sink in water.
Foam A material made of gas bubbles held in a liquid or a solid.
Gasoline A liquid fuel less dense than water, so it is buoyant in it.
Gold A dense, soft, bright yellow metal.
Honey A thick sweet liquid, denser than water.
Lead A soft, heavy gray metal that outweighs most everyday materials of the same size.
Lithium The least dense metal.
Oil A liquid that rises above water because it is less dense.
Osmium The densest known element, a hard bluish-white metal.
Platinum A dense, precious, silver-white metal.
Pumice A light volcanic rock full of gas holes; many pieces float on water.
Seawater What fills the oceans; dissolved salts make it denser than what fills most lakes.
Steel Iron alloyed with carbon; about three times as dense as aluminum.
Wood A material from trees whose density varies with the species.

Layers, Currents and Convection 22

Atmosphere The air around Earth, which grows less dense with height.
Cold Describes water that is denser than warm water.
Contract To shrink in volume, as substances usually do when they cool.
Convection Heat transfer in which warmer, less dense fluid rises and cooler, denser fluid sinks.
Current A flow of water or air; one kind is driven by a difference in density.
Dead Sea A salt lake so dense that swimming in it is much like floating.
Deep Far below the surface, where the water of the sea is calm.
Emulsion A mixture of liquids that normally will not blend, as in a vinaigrette.
Freshwater Describes lakes and rivers; what fills them is less dense than the sea.
Halocline A layer in a body of water where the saltiness changes sharply with depth.
Ice Frozen water; it floats because the solid is less dense than the liquid.
Lake An inland body of water in which a thermocline can form.
Layer A level of fluid that rests above or below another of different density.
Mixing The up-and-down stirring of water that stable layers hold back.
Ocean The body of salt water in which a thermocline divides the mixed top from the calm deep.
Pycnocline The layer in a body of water where density changes fastest with depth.
Salinity How salty a body of water is: how much salt is dissolved in it.
Sediment Loose solid particles carried by wind, water or ice and then dropped.
Settle To sink slowly to the bottom of a liquid.
Stratified Arranged in stable layers by density, as the water of a lake can be.
Thermocline A layer of a lake, ocean or atmosphere where temperature changes sharply with depth.
Thin Describes air of low density, as it is at high altitude.

Questions and answers

What is the formula for density?

Density is mass divided by volume, written ρ = m/V with the Greek letter rho. A block with a mass of 20 grams and a volume of 10 milliliters has a density of 2 grams per milliliter.

Why do some objects float and others sink?

An object with an average density greater than the fluid around it tends to sink, because it weighs more than the fluid it displaces. A less dense object floats, and displaces fluid equal in weight to itself.

What is the difference between density and buoyancy?

Density is a property of a material: its mass for each unit of volume. Buoyancy is a force: the upward push of a fluid on an object in it, equal to the weight of the fluid the object displaces.

Why does ice float on water?

Ice is about 8.3 percent less dense than liquid water, an unusual property for a solid. So it floats, which keeps bodies of water from freezing from the bottom up.

Does the density word search print with an answer key?

Yes. The puzzle prints on one sheet of Letter or A4 and its key, the grid with every word ringed, on a second. With Show clues, not words ticked, Float is listed as "To rest at the top of a fluid without going under."
