What is the equation to find density

d = m/v

What are the molecules like in a solid?

In a solid, these particles are packed closely together and are not free to move about within the substance.

What are the 2 forcees acting on an object as it enters water?

Gravity and Buoyancy

100

What does pressure mean?

Pressure is a measure of how much force is acting on an area.
200

What are the units for density for solids and fluids?

g/cm3 for solids, g/mL for fluids

200

What are the molecules like in a liquid?

In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another.

200

What is viscosity?

Viscosity is a measure of a fluid's resistance to flow.
200

What is Archimedes Principle?

When an object is placed in water and it displaces water.

200

What does compressibility mean?

The ability of something (such as a fluid) to be reduced in volume or size under pressure.

400

What is density?

Mass per unit volume.

400

What are the molecules like in a gas?

In gases the particles move rapidly in all directions, frequently colliding with each other.


400

What is Flow rate?

The flow rate is the speed at which fluid moves at.
400

Is wood a positively buoyant object?

Yes.

400

What does hydraulics and pneumatic mean?

Hydraulics is a mechanical function that operates through the force of liquid pressure

Pneumatic means filled with or operated by compressed air. In general, pneumatic means related to air or wind.



600

What are the 3 formulas used for density?

D = M ÷ V

M = D x V

V = M ÷ D

How are liquids different from solids? Give 3 examples 

 1. A solid is a state of matter that has a definite shape and volume.    A liquid is a state of matter that has volume but no definite shape. 

2. A liquid takes the shape of the container that holds it.       A solid has a shape of its own.

3. Solids are strong, tough, elastic, ductile, and flexible.         liquids are not.


600

The 3 factors that affect flow rate are?

temperature, size of particles and internal friction.

600

Is Rock a positively buoyant object?

No

600

What is the equation to find pressure?

P = F/A

P= Pressure

F = Force

A = Area

1000

What is average density?

The average density is the total mass of a region divided by the total volume of that region.
1000

Whats heavier 20 pounds of bricks or 20 9.07 liters of water?

Neiter they are the same!

1000

(Volume over time) or (ml over s) is what equation?

to determine the flow rate

1000

Do hot air balloons have buoyancy?

Yes.

How is Pascal's Law connected to hyraulics?

Pressure gets equaly sent out.
