Physical science chapter 9
| Term | Definition |
|---|---|
| TE | Total energy |
| KE | kinetic engery |
| PE | potential energy |
| Thermal energy is the ___ of all kinetic energies of its particles | SUM |
| Thermal energy is only ____ of the internal energy | PART |
| Gaining thermal energy | heating ( when molecules start moving more) |
| Loosing thermal energy | cooling |
| Heating or cooling | Transferring particle kinetic energy (the motion) |
| Temperature is the _______ of an object's kinetic energy | AVERAGE |
| Measured in degrees | Temperature |
| Advantage of using Kelvins (K) | There is NO negative values ( you can not divide by zero or come out with a negative number as your answer) |
| Fahrenheit to Celsius | 5/9 ( Fahrenheit-32) |
| Celsius to Fahrenheit | 9/5 Celsius+32 |
| Thermal expasions | When particles gain thermal energy and can move away from each other causing object to gain volume. ( why sidewalks have lines in them) |
| Electrical resistance | Increases with increasing temperature because electrons move move more randomly. |
| Viscosity | Measure of the resistance of liquids to flow |
| Heat | The quantity of thermal energy that flows from one place to another |
| Conduction | when two objects of different temperatures touch and thermal energy from the hotter one moves into the colder one. |
| Convection | thermal energy carried from one location to another by a fluid( gas OR liquid) |
| Radiation | Thermal energy that radiates from the scource outwards ( think of the sun's rays) |
| The ______ the temperature of the substance, the ______ electromagnet is emitted | HIGHER, MORE |
| Insulators | materials that resist the flow of thermal energy (Styrofoam, glass, air, cooler) |
| Vacuum of space | Best type of insulator because no particles present |
| Heat capacity (C) | the relationship between the amount of thermal energy and the temperature change caused by this |
| Heat capacity is measured in______ | Joules(J)/ Degree Celsius OR J/Kelvins (K) |
| Objects that heat up quickly, ______ down quickly | cool |
| Q=(M)(C)(change in T) | Formula for finding thermal energy (in Joules (J)) |
| Latent Heat of fusion | the amount of thermal energy exchanged per gram of material during melting OR freezing |
| Q=mL(f) | formula for Latent heat of fusion |
| Latent heat of vaporization | The amount of heat it takes to change a liquid into a gas |
| Triple point | The temperature and pressure at which the solid, liquid, and gas phases exist at the same time |
| Critical point | The temperature above which a substance will always be gas regardless of the pressure |
| Deposition | Phase change as a substance changes from a GAS to a SOLID without passing through the intermediate state of liquid |
| Sublimation | Phase change as a substance changes from a SOLID to a GAS without passing through the intermediate state of liquid |
