Dry Ice, etc.
Phase Changes
Pressure
100
This state of matter has particles which can only vibrate because they are fixed in place.
What is a solid.
100
The type of proportionality this graph shows.
What is inverse proportionality?
100
Dry ice absorbs this as it sublimes.
What is thermal energy?
100
The name given to dry ice (a solid) changing directly into CO2 (a gas), without becoming a liquid first.
What is subliming (sublimation)?
100
This type of pressure resists liquid water turning into a gas (water vapor).
What is atmospheric (air) pressure?
200
This state of matter has particles with the highest energy. These particles do not regularly touch each other but often ricochet off the walls of their container, as well as other particles in the container.
What is gas?
200
This scientist manipulated gas temperature by increasing it and found that the volume of the gas increased as well.
Who was Jacques Charles?
200
Dry ice subliming is this type of -thermic reaction.
What is an endothermic reaction?
200
The change of water vapor (gas) into tiny droplets of liquid water, such as would form clouds.
What is condensation?
200
If a ball filled with air particles has even more particles pumped into it, this happens to the pressure.
What is "the pressure increases"?
300
This state of matter has particles which are unable to move past each other.
What is a solid.
300
His law states that as volume decreases, pressure increases.
Who is Robert Boyle (Boyle's Law)?
300
The fog we see as dry ice sublimes is this compound.
What is H2O?
300
Iron (Fe) is a metal which at 3,000 Fahrenheit is a liquid. When iron cools below 2,800 degrees Fahrenheit it turns into a solid and the phase change is called this.
What is freezing?
300
This causes the pressure in a bike pump to increase.
What is reducing the volume?
400
This state of matter has particles that touch and can move past each other "like marbles in your hand."
What is a liquid?
400
A sample of gas is kept in a steel container which cannot get bigger. As this sample of gas is heated and its temperature increases, this variable increases, as well.
What is pressure?
400
Compared to boiling water at sea level, this is true about the energy needed to boil water at high altitudes.
What is "less energy is needed"
400
The name given to vaporization that takes place below and at the surface of a liquid.
What is boiling?
400
An inward force, or pull, among the molecules in a liquid.
What is surface tension?
500
This state of matter has a definite volume, but not a definite shape.
What is a liquid?
500
As you push down the handle of a bicycle pump the volume of air decreases and this variable increases.
What is pressure?
500
Name the phase change responsible for causing water droplets to form on a cold window when you breathe on it.
What is condensation?
500
Water vapor (gas) is cooled rapidly and changes directly into a solid. Frost is an example.
What is deposition?
500
This will increase in an inflated basketball which is left in the hot sunlight.
What is the pressure inside the ball will increase?
