Final Jeopardy
What is Kinetic Energy?
The energy of motion
What is matter?
Anything with mass and volume
What makes particles move?
Energy
How do particles of gas move?
They move around quickly and are very far apart
Name the seven parts of the Kinetic Molecular Theory
1.All matter is made up of very small particles2.There is empty space between particles 3.Particles are constantly moving4.Solid particles are packed together and can only vibrate5.Liquid particles can only move by sliding past each other6.Gas particles move very quickly and very far apart7.Energy makes particles move
How is PMM different from KMT?
KMT is expanded and explains movement in more detail
Why can some materials move past others?
Because some particles are farther apart
Give an example of a solid, liquid, and a gas
Answers will vary
Explain in detail what the PMM is.
PMM is the theory that explains the movement and behavior of particles in solids, liquids, and gases.
Name the 4 parts of the PMM
1. All matter is made up of very small particles 2.There are spaces between particles 3. The particles that make up particles are always moving 4. The particles are attracted to one another
What happens when you add energy to a material?
You increase the kinetic energy
What is Thermal Expansion?
What happens to the molecules in Thermal Contraction?
The process of a substance increasing in volume when it’s temperature is increased
The particles slow down, which means they take up less space
How does a thermometer show different temperatures?
The liquid inside the thermometer expands and contracts , causing it to get higher or lower
Why are electrical wires hung loosely?
In different temperatures, the particles inside the wires contract and expand. If they were strung tightly, they would break
What is Heat?
Heat is the energy transferred from one material or object as a result of different temperatures
What is Thermal Energy?
Thermal Energy is the total energy of the particles making up a substance
What would happen if two objects with different thermal energies were to come in contact?
The thermal energy from the warmer of the two would move to the colder one
What is the difference between heat and temperature?
Heat is the energy transferred fromone material or object as a result ofdifferent temperatures,while temperature is a measure of theaverage kinetic energy of the particles in a substance
What happens when you touch a hot cup of Tea?
The heat from the cup transfers into your hand, because your hand has a lower thermal energy
What is Sublimation?
Sublimation is the change of state from a solid to a gas, skipping the liquid stage
What is called when a gas changes into a liquid?
Condensation
What is Deposition?
The change of state from a gas to a solid
What is the melting point?
The melting point is the temperature at which a solid turns to liquid
What are the six terms for the changes of state
Melting, Evaporation,Condensation, Solidification,Sublimation, and Deposition
