| Question | Answer |
|---|---|
| volumne | length* width* height= volumne |
| temp. | a measure of how hot or cold an object is. |
| charles law | the principle that all gases expand equally for the same rise of temperature if they are held at a constant temperature. |
| boyle law | the principle that at a constant temperature the volumne of a confined ideal gas varies inversely with its pressure. |
| combined gas law | |
| phase change | a change from one state ( solid, liquid or gas)to another without a change in chemical composition |
| evaporation | to change or cause to change from a liquid or solid state to a vapour |
| boiling | to change from a liquid to a gaseous state, producing bubbles of gas that rise to the surface of the liquid, agitating it as they rise. |
| melting | to become liquefied by warmth or heat, as ice, snow, butter, or metal. |
| vaporization | to change or cause to change into vapour or into the gaseous state |
| condensation | the result of being made more compact or dense. |
| sublimation | to convert (a solid substance) by heat into a vapor, which on cooling condenses again to solid form, without apparent liquefaction. |
| deposition | the phase change in which a gas or vapor changes directly into a solid without first changing into a liguid. |
| endothermic change | a chemical reaction that absorbs energy from its surroundings |
| heat of fusion | the energy an object must absorb to change from a solid to a liguid. |
| absolute zero | a temp of zero kelvins |
| pressure | the result of a force distributed over an area |
| kinetic theory | the energy an object has due to its motions |
