100
The amount of thermal energy needed to raise the temperature of 1 Kg of some material by 1 degree Celsius.
What is specific heat?
100

The state of matter with the lowest kinetic energy

Solid

100

The transfer of thermal energy between colliding particles via contact. Example: You hold a mug of coffee.

What is conduction?

100

Which has more thermal energy: a glacier or a Starbucks Mocha Latte?

A glacier

100

At what temperature does liquid water change to water vapor? Use degrees C. 

100 degrees C

200

The total amount (sum) of the kinetic energy in the particles in an object.

What is thermal energy?

200

Particles are packed closely and it has a specific shape and volume.

What is a solid?

200

A material in which thermal energy moves slowly.

What is a Thermal Insulator?

200

Why is air a good insulator?

The particles in a gas, such as air, are spread out and less likely to collide into each other compared to a liquid or a solid. Thus, thermal energy is transferred more slowly in air, making it a good insulator 

200
When a gas changes into a liquid.
What is condensation?
300

The SI unit for temperature

Kelvin (K)

300

Particles in this state have a high amount of kinetic energy, and no definite shape or volume.

What is a gas?

300

The transfer of thermal energy in a fluid by the movement of fluid from place to place.

What is Convection?

300

Metal slides used to be common on playgrounds, but have now been replaced with plastic slides. Why is plastic better?

Metal is a good conductor, meaning the sun's radiation will transfer to it quickly, heating it up very fast.  Plastic is not a good conductor, so a plastic slide will heat up more slowly compared to a metal slide. 
300
When a solid changes directly into a gas

Sublimation

400

What does sand at a lake heat up faster than the lake water?

The sand has a LOWER specific heat, meaning it allows the sun's radiation to pass through it readily.  The lake water has a HIGHER specific heat, meaning it does not allow thermal energy to pass through it readily. 

400

Matter that has a definite volume but no definite shape; particles are loose and can slide over each other.

What is a liquid?

400

A material in which energy is transferred easily.

What is a thermal conductor?

400
Why do telephone wires droop in the summer time? Explain both the material the wires are made of and the thermal property they exhibit. 

The wires are made of metal and metal undergoes thermal expansion when heated, meaning the wires will expand in size when they get warm in the summer.  This expansion causes them to droop. 

400

Vaporization that occurs at the surface of a liquid.

Evaporation

500
Thermal energy that flows from something at a higher temperature to something at a lower temperature.
What is heat?
500

4th state of matter, made up of both positively and negatively charged particles (ions).

What is Plasma?

500
The transfer of energy by electromagnetic waves.
What is radiation?
500

Metal is a good conductor of heat.  So why is a Hydroflask, made of a double metal wall design, such a good insulator of beverages? How is this so?

A Hydroflask (or other thermos) is made with a double wall design, with two layers of metal filled with an air gap in between.  The air gap is what insulates the beverage, meaning it does not allow thermal energy to pass through the walls of the container easily.  This keeps the heat inside (if the beverage is warm) or keeps the heat outside (if the beverage is cold).

How do blankets keep you warm? Use the term "thermal energy" in your answer. 
Blankets are good insulators, meaning they do not allow thermal energy to pass through them easily.  When your body releases heat, the blanket traps the heat and keeps it close to your.
