| 284705056 | Thermodynamics | the study of heat and how particles move. | |
| 284705057 | Heat | the flow of energy from one object to the next due to temperature differences. Hot will always go to cold as hot particles are more chaotic and high chaos goes to low chaos. | |
| 284705058 | Temperature | comparison of 2 objects and how hot or cold they are. | |
| 284705059 | Thermal energy | how much potential and kinetic energy are in objects. It is the internal energy. Hot objects have a higher thermal energy. | |
| 284705060 | Conduction | 2 objects physically touch and the particles collide. The energy from the "HOT" object is transferred to the "COLD" therefore - the "HOT" cools down and the "COLD" heats up. | |
| 284705061 | Conductor | allows heat to flow easily. | |
| 284705062 | Insulator | an object that does not allow heat to flow easily. | |
| 284705063 | Absolute Zero | the lowest possible temperature, where there is no longer any thermal energy. | |
| 284705064 | Convection | the flow of heat due to difference in densities. | |
| 284705065 | Thermal Expansion | When an object is heated it expands. When it is cooled it contracts. | |
| 284705066 | Radiation | transfer of heat due to electromagnetic waves. It does not need particles as it is a wave. | |
| 284705067 | Blackbodies emitters | black object that absorbs more heat and therefore is a better emitter. | |
| 284705068 | Specific heat | the amount of energy needed to raise 1 kg of a substance by 1ºC/K. | |
| 284705069 | Heat of vaporization | the amount of energy needed to change 1 kg of liquid to a gas. | |
| 284705070 | Boiling | For this to occur, particles must move fast enough to break surface tension and the liquids pressure must exceed air pressure. Higher elevations and cold days mean less air pressure and therefore faster boiling. | |
| 284705071 | Heat of fusion | The amount of energy needed to change 1 kg of a solid to a liquid (melting). | |
| 284705072 | Calorimeter | a device that does not allow heat to flow in or out. | |
| 297947639 | Convection current | An object gets heated > decreases in density and expands > it rises > it cools and contracts > it sinks. | |
| 297947640 | Zeroeth Law | If A is the same temperature as B, and B is the same temperature as C, then A and C must be in thermal equilibrium. | |
| 297947641 | 1st Law | The internal energy (thermal energy) of the system is due to heat added and work done on the system. -W means work done ON the system, while +W means work done BY the system. | |
| 297947642 | 2nd Law | Entropy (chaos) in the universe must always increase. Particles go from high chaos to low chaos. | |
| 297947643 | Isobaric | Pressure does not change. (Charles Law) | |
| 297947644 | Isovolumetric | Volume does not change. (Gay-Lussac Law) | |
| 297947645 | Isothermal | Temperature does not change. (Boyle's Law) | |
| 297947646 | Adiobatic | Temperature can change, but no thermal energy will be lost or gained. | |
| 297947647 | Heat engines | Use heat and transform it into mechanical energy. | |
| 297947648 | Carnot cycle | An engine with 100% efficiency. Does not exist yet. |
