Liquid and Gas
The change in state from a liquid to a gas is _________________.
Vaporization
The two types of changes in state between a solid and liquid are _____________.
Melting and freezing
__________________ occurs when the particles of a solid gain enough energy they change right to a gas.
Sublimation
Pressure = __________ / ___________
Force / Area
Define vaporization.
Change in state from a liquid to a gas.
Two types of vaporization are:
Boiling and evaporation.
When you freeze a liquid, its particles (speed up or slow down).
Slow down
One example of sublimation is ___________________.
Dry ice
When the pressure inside of a liquid equals atmospheric pressure, the liquid _____________________.
boils
Define melting point and boiling point.
The temperature at which a solid melts, the temperature at which a liquid boils.
Describe what you see when a liquid boils. Do you see these things when a liquid evaporates?
Any acceptable answer. (bubbles, steam/water vapor, etc.)
When a solid changes into a liquid, its particles (Speed up or slow down)
Speed up
Some fog machines use ______________________ to create fog in movies.
Dry Ice
In locations high above sea level, where there is less atmospheric pressure, it takes (less or more) heat to boil the water.
Less
Kinetic energy is ____________________. Potential energy is __________________.
energy of motion, stored energy
Vaporization that takes place only on the surface of a liquid is ______________. Give an example.
Evaporation, when a puddle dries up
You (can or can't) use a substance's melting and boiling point to identify a substance.
Can
During sublimation, particles of a solid do not pass through a _____________ state.
liquid
In locations below sea level, where there is a higher atmospheric pressure, it takes (more or less) heat to make water boil.
More
Define temperature.
A measure of the average kinetic energy of the particles in a substance.
Vaporization that takes place throughout the whole liquid is __________________. Give an example.
Boiling, when you boil pasta water, etc.
Changes of state from a solid and a liquid involve a change in _________.
thermal energy
At ordinary atmospheric pressure, carbon dioxide cannot exist as a _____________.
Liquid
The pressure a gas applies is (greater or lesser) the more its particles collide with a surface.
Greater
Thermal energy is __________________________________________
The total amount of kinetic and potential energy in a substance.
