### Three-Phase Model of Matter

How do we change the phase or temperature of matter? adding or removing energy (ex: transfer it through heat)
Energy Interaction Diagrams shows how energy interacts between substances
Energy Forms Thermal, Bond, Kinetic, Potential (gravity), and Potential (spring)
Indicators of energy transfer For thermal energy: temperature; For bond energy: amount of substance in a "higher" phase (between initial and final phase)
How do you set up an Energy Interaction Diagram? Define system Define interval, Track indicator and energy changes Open or closed system Energy Equation
System: H20 (initial = -10C, final = 15C) How can we model how much energy is needed to melt ice initiatlly at -10C, and bring it to 15C Note each phase and temp change for the substance: Ice. Thermal Energy. (initial -10C and final 0C); Mixed. Bond Energy. (initial all solid and final all liquid) Water. Thermal Energy. (initial 0C and final 15C

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
