Kinetic Energy(INV 4)

100

If I heat water in a closed system (Ex. Thermometer), the _____ energy will increase. 

What is kinetic energy. 

(SIZE and AMOUNT DON'T CHANGE)

200

The way particles are organized in solids, liquids, and gasses are different, but the particles are always in _________. 

What is motion. 

300

In compression, I take away space by adding pressure. In __________ I take away space by removing heat. 

What is contraction. 

Energy Transfer (INV 5)

100

The measurement of heat. 

What are calories?

cal= m x ΔT

200

The temperatures of a cup of water and the air around it are both room temperature. They are sharing energy. This would be called a state of _________. 

What is equilibrium?

(Temperature is the same, and energy is moving back and forth between the two). 

300

If I mix hot and cold water together, the final temperature will be the ________ of the two temperatures. 

What is the average?

Solutions (INV 7)

100

This is the name for a solute and a solvent combined. 

What is a solution? 

200

This is how you would separate a solute from a solvent. 

Ex. Separate salt from water. 

What is evaporation. 

300

If a substance does not dissolve in water, it is not part of the solution (Ex. Chalk), we would use this to separate it from solution (Ex. Water)

What is a filter/filter paper? 

Phase Changes(INV 8)

100

If I boil water, bubbles form, the bubbles are made of __________. 

What is Water (or Water Vapor). 

200

The temperature at which a substance turns from a liquid to a solid (or solid to liquid). 

What is the Melting/Freezing point. 

300

If a substance changed phases from a gas to a solid. 

What is deposition. 

Common Sense

100

Solid to Liquid. 

What is melting?

200

Phase changes are not _______________. 

What is a chemical reaction. 

300
