| Question | Answer |
|---|---|
| what are the three main states of mater? | solid, liquid, and gas |
| this state of matter has a definate volume but not a shape | liquid |
| this state of matter has a definate shape and volume | solid |
| what is the kinetic theory of matter? | it states that all things of matter are in constant motion |
| this state of matter has no definate shape or volume | gas |
| what is the kinetic theory of gases | ity states that it is the constant motion of particles in a gas allows a gas to fill a container of any shape or size. |
| what is pressure | pressure is the result of a force distributed over an area |
| what happens when you reduce the volume of the gas? | it would increase its pressure if the temperature and number of the partials are constant |
| what is the charles law? | it states that a volume of a gas is directly proportional to its temperature in kelvins if the pressure and the number of particles of the gas are constant |
| state what the boyle's law is | it 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 a phase change? | a phase change is the reversible physical change that occurs when a substance from one state of matter to another |
| what are the common phase changes? | melting,freezing,vaporization,condensation, sublimation,and deposition |
| what is endothermic? | the system absorbs energy from its surroundings |
| what is exothermic? | the system releases energy to its surroundings |
| what is vaporization | an endothermic proces that turns a liquid to a gas. |
