Question | Answer |
Which state of matter has a definite shape and a definite volume? Example: Copper wire | Solids have definite shapes and definite volumes. |
Which state of matter takes the shape of the container it's in and has a constant volume (because of the forces of attraction keep its particles close together)? Example: Orange juice | This state of matter is a liquid. |
Which state of matter can fill a container of any shape or size because of the constant motion of its particles? Example: Helium | This state of matter is a gas. |
What type of energy do objects have because of their motion? | Objects have kinetic energy due to their motion. |
Pressure | The result of a force distributed over an area. |
Absolute Zero | A temperature of zero Kelvins |
Chales' Law | States that the volume of a gas is proportionate to its temp. in Kelvins if the pressure and number of particles of gas are constant. |
Boyle's Law | States that the volume of a gas is inversely proportional to its pressure if the temp. and number of particles are constant. |
Phase Change | The reversible physical change that occurs whena substance changes from one state of matter to another. |
Endothermic | The change where a system absorbs energy from its surroundings. |
Heat of fusion | The amount of energy absorbed during a phase change that varies from substance to substance. |
Exothermic | The type of change when a system releases energy to its surroundings. |
Vaporization | The phase change where a substance changes from a liquid to a gas. |
Heat of Vaporization | The amount of energy absorbed when a liquid changes to a gas. |
Evaporation | The process that changes a substance from a liquid to a gas at temp.s below the boiling point. |
Vapor Pressure | The pressure caused by the collisions of vapor during vaporization. |
Condensation | The phase change in which a substance changes from GAS OR VAPOR TO A LIQUID. |
Sublimation | The phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first. |
Deposition | The phase change where a gas or vapor changes into a solid without changing into a liquid first. |
