16
Q

What is Archemedies Principle?

A

The Buoyant force on an object is equal to the weight of the fluid dispalced by the object.

17
Q

What is Pascal’s Prinicple?

A

Pressure applied to a fluid is carried all throughout the fluid.

18
Q

What principle explains how pascal’s principle works?

A

Pascal’s Principle, you should know this.

19
Q

What is Buoyancy?

A

The ability of a fluid to exert and upward force on an object imersed in it.

20
Q

Which Principle explains why some objects float and others sink?

A

Archimedes’s Principle

21
Q

What is Bernoulli’s Principle

A

Fluid velocity will increase when the flow of a fluid is restricted.

22
Q

What happens to the particles in matter when it’s heated?

A

They gain more kinetic energy and vibrate faster.

23
Q

Increasing what raises the boiling point of a liquid?

A

Pressure.

24
Q

State the 4 points of kinetic theory.

A
  1. all matter is made of tiny atoms.
  2. particles are in constant random motion
  3. The particles collide with each other and their container walls.
  4. Their Collisions don’t make them lose KE.
25
Q

Define Viscocity.

A

The resistance of a fluid’s flow.

26
Q

As the temperature of a gas increases, the volume of the gas will do what if the pressure stays the same?

A

Increase, the gas will move faster and push against the walls of their container, increasing the volume.

27
Q

As the volume of a gas decreases, the pressure of the gas will do what if the temperature stays the same.

A

Increase, the gas will get cramped into a smaller space and push harder against is containers walls.

28
Q

What is the formula for density?

A

Density = Mass / Volume

29
Q

What is the formula for Pressure?

A

Pressure = Force / Area

30
Q

What is the formula for pascal’s principle?

A

Force in / Area in = Force out / Area out

31
Q

What is the formula for Boyles’ principle?

A

Pressure1 x Volume1 = Pressure2 x Volume2

32
Q

What is the formula for Charles’s principle?

A

Volume1/ Temperature1 = Volume2/ Temperature2

33
Q

What is the SI unit for Denstiy?

A

g/cm^3
