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
