What is Change of State
What is the fourth state of matter beyond solid, liquid and gas?
What is Plasma
The state of matter that has strong particle attraction and vibrates in place.
What is a solid
Water on the stove turns into steam. What change of state is happening?
What is boiling/liquid to gas.
The change of state of liquid to a gas
What is evaporation
The state that has a definite volume but not definite shape.
What is a Liquid
In which state of matter do particles only vibrate in place?
What is a Solid
Dry ice seems to disappear when left out. What is going on?
What is Sublimation
The change of state from a gas to a liquid?
Name an example of plasma.
What is stars, lighting, florescent light, plasma balls.
What happens to the motion and spacing of particles when a solid becomes a liquid?
What is the particles move faster and become more loosely connected.
If a balloon is pulled down to the bottom of a pool, what will happen to the balloon?
What is the pressure of the air particles inside the balloon will increase.
The conversion of a liquid vapor when the vapor pressure of a liquid equals the atmospheric pressure?
What is Boiling
Why can gases be compressed so much more than solids or liquids?
What is because gas particles are far apart with mostly empty space between them.
For a solid to melt, particles must ___ energy to overcome some of their attractions to each other.
What is absorb
If a basketball that was inflated inside was left outside on a cold day, what would happen to the ball?
What is the volume of the air would decrease and the ball would become smaller.
The process of which a solid changes directly to a gas.
What is Sublimation
Compare how energy levels differ among the four states of matter.
What is solids have the lowest average particle energy, liquids have more, gases have even higher, plasma has the highest energy.
For a fixed amount of gas at a constant pressure rate, the volume of the gas decreases as the ___ decreases.
1000 BONUS POINTS: Who's law is this?
What is Temperature.
BONUS: Charles's Law
A kettle on the stove boils water, and steam rises from the spout. Explain why the water’s temperature stays the same at 100C while it is boiling, even though heat and energy is being added.
What is the heat is used to change the water into steam, not to make it hotter.
