What model best depicts a solid with more than 1 type of particle(atom or molecule) within it?
What models could represent a solid? Choose all that apply.
What models could represent a liquid? Choose all that apply.
Which models best show a liquid mixed with another substance? Choose all that apply.
Which model(s) could show a solid in a liquid? Choose all that apply.
What statement best explains why water boiled well below the boiling point in the boiling water demo?
Ice water sped up the molecules of the water, lowering the volume of the water which allowed a lower boiling temperature.
Ice water lowered the temperature of the gas, which slowed down the gas molecules, making them take up less space and finally lowering the pressure.
The gas above the water created more pressure when the ice water was poured on it.
The ice water lowered the pressure of the water. Allowing the water to boil at a lower temperature
What phase change happens to dry ice (CO2) at room temperature?
Deposition
Sublimation
Melting
Vaporiization
In the super heated steam demo, explain why the steam disappeared.
The molecules stopped coming out of the pipe.
The molecules were going through condensation so you couldn't see them.
The kinetic motion of the molecules slowed down so you couldn't see them.
The kinetic motion of the molecules was too fast to see
In the super heated steam demo, which best explains the reason the match ignighted.
The molecules stopped coming out of the pipe.
The molecules were moving at a high rate of speed and created enough friction to strike the match.
The kinetic motion of the molecules slowed down allowing the match to ignite itself.
The blow torch lit the match.
What term describes a gas changing to a solid? For Example, when water vapor hits glass and frost is formed.
Deposition
Sublimation

In the boiling water demo, removing the stopper caused a popping sound because pressure was (a) and air was moving (b) the bottle.
Latent heat is
the heat absorbed or released at a boiling process during a change of phase
the heat absorbed or released at a constant temperature during a change of phase
the heat absorbed or released at a constant temperature during a change of phase of 1 kg object
the heat absorbed or released by an object to increase or decrease its temperature by 1 degree Celcius
If water is left to boil, what statement is not true?
All the water will eventually evaporate.
The temperature of the water will eventually reach 200°C.
The temperature of the water will remain at 100°C until it evaporates.
The beaker with only 100 mL of water will boil away faster than the beaker with 200 mL of water.
