(D measured in g/cm cubed)
Formule: D= m/v

What is a fluid?
What is materials that can flow and have no definite shape.

What is a buoyant force?
What is the upward force on an object in a fluid exerted by the surrounding fluid.
200
What is a rectangular solid? How would you calculate the volume of it?
What is a six-sided block in which all sides are rectangles.
Formula: V=LxWxH
200
What is pressure, and what is its formula?
What is the force per unit of area applied to the surface of an object. P (in pascals)= F/A
200
True or False(correct the statement if it is wrong):
The buoyant force on an object in a fluid increases as depth increases.
What is False. The buoyant force does not increase as depth increases.

How do you calculate the volume of an irregular solid?
What is subtracting the volume of the solid in the container with liquid in it from the volume of the liquid itself.
300
What is atmospheric pressure?
What is the force exerted per unit area by air particles.
300
What is Archimedes's Principle?
What is the buoyant force on an object = the weight of the fluid the object displaces.
400
How do you calculate the mass of a fluid?
What is subtracting the mass of the fluid in its container from the mass of the container itself.

Calculate: I have a box full of books I want to move. I push a force of 250 N. The surface area of the box is 5 ft. squared. How much pressure am I applying to the box?
What is 50 Pascals.

Explain how a steel cube sinks, but a steel boat floats.
What is the greater the volume of an object has, the less density it has making the object less dense than the fluid it is in, so it floats.

What is the density of an object that weighs in at 10 grams, and has a volume of 5 cm cubed?
What is 2 g/cm cubed.

Calculate: I tried to push my cabinet. I exerted a force of 210 N, and I know the pressure I exerted was 30 Pascals. What is the area of the surface?
What is 7 ft. squared.

What is a hydrometer, and how does it work?
What is an instrument that measures the density of a liquid. You place it in the water and it has marks that measures the length that it is submerged in water. From there you can calculate the density.
