Science - Chapter 8: Density

What is weight?

• The force of gravity acting down on an object

• The force of buoyancy acting upward on an object

• The amount of matter that makes up an object

• The amount of space an object/substance takes up

What is mass?

• The amount of matter that makes up an object or substance

• The amount of space an object/substance takes up

• the force of gravity acting down on an object

• The weight of the object is equal to the weight it displaces

What is volume?

• The amount of space an object or substance takes up

• The downward force on an object

• the force of buoyancy pushing an object further down into a substance

• How loud a sound plays, for example, playing music full blast on a speaker

What does it mean to displace?

• To forget where something was put

• To put something in the wrong spot

• To take the place of

What is density?

• a measure of the mass per unit volume of a substance

• a measure of the weight per unit mass of a substance

• a measure of the mass per unit weight of a substance

What is characteristic property?

• a property that makes a particular substance that distinct from others

• a property that makes multiple substances the same

• a property that makes a singular substance the same as a solid

What is buoyancy?

• The upward supportive force on an object in a fluid

• The downward, unsupportive force on an object in a fluid

What is a swim bladder?

• A controllable, balloon-like chamber that allows fish to alter their buoyancy

• compartments in a ship or submarine that take in water to keep the ship stable or to help a submarine dive below the surface

• The upward supportive force on an object in a fluid

What are ballast tanks?

• Compartments in ships or submarines that take in water to keep the ship stable or help a submarine dive below the surface

• Compartments in airplanes or jets that take in air to keep the plane stable or help a jet fly faster

• A controllable, balloon-like chamber that allows fish to alter their buoyancy

What is the relationship between weight, mass, and volume?

• They are all attributes of an object. If one doesn't work, none of them will. They affect each other most of the time.

• None of them are attributes of objects. If one doesn't work, the others still can. They do not affect each other at all.

• Weight and mass are the same while volume is the only one that's different.
