Changing States
I like to move it, move it
Water, Water everywhere
Got Gas?
Hodge Podge
100
Change of state in which a solid becomes a liquid
What is melting
100
Atoms within a solid have this type of movement
What is vibration?
100
A force that tends to pull adjacent parts of a liquid's surface together, thereby decreasing surface area to the smallest possible size is called this
What is surface tension?
100
This is a hypothetical gas that perfectly fits all assumptions of the kinetic molecular theory
What is an Ideal Gas?
100
The dynamic condition in which two opposing changes occur at equal rates in a closed system...everything is balanced here
What is equilibrium?
200
Change in state in which a liquid becomes a gas
What is evaporation?
200
Atoms within a liquid can perform this type of movement
What is flow?
200
The attraction of the surface of a liquid to the surface of a solid is called this
What is capillary action?
200
In an ideal gas, all collisions between gas particles are THIS p - one in which there is no net loss of total kinetic energy
What is an elastic collision?
200
This is the amount of energy as heat that is needed to vaporize one mole of liquid at the liquid's boiling point at a constant pressure
What is the molar enthalpy of vaporization?
300
Solid CO2 can become a gas without going through the liquid phase change. This is called...
What is sublimation?
300
Gas particles move independently and randomly. They do this off of each other
What is bounce?
300
The attraction that water molecules have for each other is referred to as this.
What is cohesion?
300
This is a gas that does not behave completely according to the assumptions of the kinetic-molecular theory
What is a real gas?
300
This is a graph of pressure versus temperature that shows conditions under which the phases of a substance exist
What is a phase diagram?
400
Change of state when a gas becomes a liquid
What is condensation?
400
In relation to motion, raising the temperature of any state of matter will cause the atoms to do this
What is move faster or speed up?
400
The attraction that water molecules have to other surfaces is called this. It is also the reason water forms a meniscus inside a container.
What is adhesion?
400
This is theprocess by which gas particles pass through a tiny opening
What is effusion?
400
In a phase change graph of heating ice until it is boiling, there are flat portions in the graph instead of just a stready climbing of the temperature. The heat energy in the flat portions is being used to break what?
What is break bonds between the phases? (solid to liquid then liquid to gas)
500
The gas form of water in the air around us can turn into a solid on the ground forming frost. The phase change in which a gas becomes a solid is called this
What is deposition?
500
At absolute zero, all particles are theorized to do this.
What is cease all motion/ stop moving/ etc
500
Water works with soap to clean your skin because soap molecules have two ends -- the hydrophobic end, which attracts oils and dirt, as THIS end, which is attracted to the water.
What is hydrophyllic?
500
The spontaneous mixing of particles of two substances caused by their random motion, especially in gases, is referred to as this.
What is diffusion?
500
This is the amount of energy as heat required to melt one mole of solid at the solid's melting point
What is molar enthalpy of fusion?
