|---|---|---|---|---|---|
| What are the the properties of a liquid? | The properties of a liquid are that it has a definite volume, but no definite shape.
🗑
|
||||
| How are the properties of a solid and gas different? | The properties of gas are the complete opposite of the properties of a solid. Gas has no definite shape or no definite volume, while a solid has both definite shape and volume.
🗑
|

| What type of energy is moving? | Kinetic energy.
🗑
|
||||
| What is the result of force distributed over an area? | Pressure.
🗑
|
||||
| What does absolute zero mean? | Absolute zero is the temperature of 0K. Nobody has ever been able to produce a temperature of absolute zero.
🗑
|
||||
| Which law states that the volume of a gas is directly proportioned to its temperature in kelvins if the pressure and the number of particles of the gas are constant? | The law is Charles's Law.
🗑
|
||||
| What is Boyle's Law? | Boyle's Law states that the volume of a gas is inversely proportional to its pressure if the temperature and the number of particles are constant .
🗑
|
||||
| What is the reversible physical change that occurs when a substance changes from one state of matter to another. | Phase change
🗑
|
||||
| How do endothermic and exothermic compare and contrast? | Endothermic is when energy is absorbed, while exothermic is when energy is released.
🗑
|
||||
| What is heat of fusion? | Heat of fusion is the energy required to change a gram of a substance from the solid to the liquid state without changing its temperature.
🗑
|
||||
| What is the phase change when a substance changes from a liquid to a gas? | The phase change is called vaporization.
🗑
|
||||
| How is heat of vaporization similar to heat of fusion? | They are both the energy required to create a phase change per gram without changing the temperature, but heat of vaporization is the conversion of liquid into a gas.
🗑
|
||||
| What is the process of evaporation? | Evaporation is the process that changes a substance from a liquid to a gas below the substances boiling point.
🗑
|
||||
| What is the pressure exerted by water vapor in the atmosphere? | Vapor pressure
🗑
|
||||
| What is condensation, and what is an example of it? | Condensation is the process that changes a gas into a liquid. An example is dew.
🗑
|
||||
| What is the difference between sublimation and deposition? | Sublimation is the phase change in which a solid transforms directly into a gas without passing through the liquid phase while deposition is when a gas transforms directly into a solid without passing through the liquid phase.
