Terms in this set (31)
Solid to liquid, absorbing heat
Liquid to solid, releasing heat
Surface of a liquid (ONLY) turning into a gas, absorbing heat.
Boiling point of a liquid becoming a gas.
Gas to liquid, releasing heat
Solid to Gas, no liquid state, absorbing heat
Gas to solid, no liquid state, releasing heat
Definite shape and definite volume
Indefinite shape and definite volume
Indefinite shape and indefinite volume
Particles in a solid
The low kinetic energy of the particles cannot overcome attraction to each other.
Particles in a liquid
Particles cannot overcome attraction to each other, but can slide past, or roll over other particles.
Particles in a gas
High kinetic energy of the particles overcome attraction to each, and can move away and toward each other.
Bernoulli's principle states:
Gas moving faster creates lower pressure area.
What determines whether a liquid changes to a solid at freezing point?
A liquid changes to a solid when it is releasing heat.
By decreasing the volume of a gas, you increase its pressure.
Why boats float:
Pressure exerted on a gas and is transmitted equally throughout the fluids.
Relationship of temperature and volume in a gas
A solid that lacks a crystalline structures that melt over a range of temperature, not a specific temperature.
Heat of fusion
Amount of energy required to make a liquid into a solid
Heat of vaporization
Amount of energy required to make a gas into a liquid.
What are kinetic theory assumptions?
1) All gases are made up of particles.
2) Particles are in constant, random motion.
3) The particles have collisions with their container's walls.
4) There is so little energy lost by colliding, it does not matter.
What is density?
The volume divided by mass. More dense than water, it sinks. Less dense than water, it floats.
A state of matter where particles are moving so fast that they knock off electrons to create charged particles.
The state of matter most found in the universe.
Examples of plasma
Lightning, florescent lights
Potential theory assumptions
Particles that are farther apart have more potential energy than particles that are close together.
Example of sublimation
Carbon Dioxide (dry ice) goes from a solid to gas, no liquid state.
Example of deposition
Frost on the windshield in winter. Water as a gas becomes a solid on glass without being a liquid.
An explanation of how particles of gases behave.
