Module 14 Study Guide Flashcards
Prepare for Module test or something.
What is Temperature
The measure of the average KE of all the particles in an object are. Or in other words how hot or cold something is.
What is the SI Unit of Force
Newtons
What is Viscosity
How “Thick” or “Thin” a fluid Flows.
What is sublimation
It’s when a solid changes to a gas and skips the liquid faze.
What is an amorphous solid?
A solid that lacks a crystiline structure and has a weird melting point
The changing of a liquid ot a gas is called?
evaptoration
what is the most common state in the universe?
Plasma
What is a solid?
A mass of particles that
1. usually have a crystiline structure
2. Low KE
3. They have a definite shape and volume.
What is a liquid?
A mass of particles that
1. Have a definite VOLUME
2. Somewhat Low KE
3. They take the shape of their container
What is a gas?
A mass of particles that
1. Move in constant random motion
2. Fit to the the shape of their container
3. Don’t have a fixed or definite volume
4. Colide with eachother and their containers walls
What is plamsa?
The most common state in the universe that
1. Is completely stripped of electrons
2. Has enough energy to overcome attractive at an atomic level
Most matter does what when heated?
Speeds up
Compared to most substances, water is a weirdo because it does what when it becomes a solid?
It expands
What is the AMOUNT OF ENERGY needed to change a SOLID to LIQUID called? It’s the heat of what.
Fusion
What is the AMOUNT OF ENERGY needed to change a LIQUID to a GAS called? It’s the heat of what.
Vaporization
What is Archemedies Principle?
The Buoyant force on an object is equal to the weight of the fluid dispalced by the object.
What is Pascal’s Prinicple?
Pressure applied to a fluid is carried all throughout the fluid.
What principle explains how pascal’s principle works?
Pascal’s Principle, you should know this.
What is Buoyancy?
The ability of a fluid to exert and upward force on an object imersed in it.
Which Principle explains why some objects float and others sink?
Archimedes’s Principle
What is Bernoulli’s Principle
Fluid velocity will increase when the flow of a fluid is restricted.
What happens to the particles in matter when it’s heated?
They gain more kinetic energy and vibrate faster.
Increasing what raises the boiling point of a liquid?
Pressure.
State the 4 points of kinetic theory.
- all matter is made of tiny atoms.
- particles are in constant random motion
- The particles collide with each other and their container walls.
- Their Collisions don’t make them lose KE.
