States of Matter & Thermal Energy

Liquid or Soild?

100

I am slippery but only when melt.

ice CUBE

200

I have the most molecules

Soild

300

I don't have more molecules than the most but I have a lot

Liquid

400

Its peanut butter a Solid or Liquid

 ^{LIQUID !!!}

500

what is jello

Its BOTH!

Matter Definitions

100

A definite shape & volume Molecules tightly packed with a regular pattern & vibrate in place.

Soild,Liquid, or Gas?

Soild

200

 A definite volume but no definite shape. Molecules are loosely packed & flow against each other.

Solid, Liquid, Or Gas? 

 Liquid

300

No definite volume and no definite shape. Molecules are very far apart and can move

Solid,Liquid, or Gas?

Gas

400

_____ is anything that has mass and takes up spaces. The three fundamental states of matter are Solid,Liquid, & Gas

Matter

500

Changes in states are the result of energy being added or removed.

Solid,Liquid,Gas? 

(trick question)

ALL!

Thermal Energy Definitions

100

_______ is the energy transferred from a warmer object to a cooler object.

Heat

200

Heating a substance can cause its particles to move more ________

quickly.

300

 _________ is a measure of the average kinetic energy of the particles in a substance.

Temperature.

400

 The  _______ scale has a freezing point at zero degrees. However, in the United States where we typically use Fahrenheit, the freezing point is at 32 degrees.

Celsius

500

__________- the lowest temperature possible with zero kinetic energy.

Absolute Zero

Heat Transfer Definitions

100

_____________

• The transfer of energy as heat occurs when particles collide.

Conduction

200

•  __________ are materials that easily carry heat or electric current.

Conductors

300

____________ are materials that are poor carriers of heat or electric current.

Insulators

400

___________  
The transfer of energy by electromagnetic waves. This is the only form of heat transfer that does not require matter. 

Radiation  

500

______________

Type of heat transfer that occurs through the movement of fluids (liquids and gases).

Convection

More Heat Transfer Definitions

100

 ______________

• When a substance or material is heated, its temperature rises. But the temperature does not rise at the same rate for all materials.

Specific Heat

200

• The amount of heat required to raise the temperature depends on the material’s ________________ and _____.

chemical make up & mass

300

• As thermal energy of matter increases, its particles usually spread out, causing the substance to expand. This is true for almost all types of matter. This expansion during heating is called __________________.

thermal expansion

400

• When matter is cooled, the opposite happens. Thermal energy is released causing the particles to slow down and move closer together.  This is called  __________.

contraction

500

Uneven heating (warm air/water rising and cold air/water sinking) can result in convection ___________.

Currents
