| Question | Answer |
|---|---|
| Heat flows from hot to... | cold |
| What is an object's thermal energy? | Heat |
| What is the Kinetic-molecular model? | atoms, molecules, ions, and subatomic particles are in constant motion. |
| What is potential and kinetic energies together | total internal energy. TE=KE+PE |
| When can thermal energy be measured? | when it is being transferred to one system from another. |
| What is the sum of all kinetic energies of a system? | Thermal energy |
| What is it called when molecules start moving more? | Gaining kinetic energy |
| What happens when Gaining Kinetic Energy | There is an increase of thermal energy and temperature |
| loss of thermal energy= | falling temperatures |
| gain of thermal energy= | rising temperatures |
| What tool is used to measure temperature | a thermometer |
| Advantage of Kelvin scale | NO negative values |
| celsius= | 5/9 (Farenheit-32) |
| Farenheit= | 9/5 Celsius+32 |
| Thermal expansion | Particles gain energy and move away from each other. This makes the object expand and get bigger. |
| Electrical resistance | Measures how well electricity is conducted. |
| Viscosity | the measure of resistance of liquids to flow. |
| Heat | quantity of thermal energy that flows from one place to another |
| what does heat transfer through? | Conduction, convection, and radiation |
| conduction | two objects with different temperatures touch. The thermal energy from the hot object moves to the cool object. |
| What are two good conductors of thermal energy? | diamonds and metals |
| What are two bad conductors of thermal energy? | plastic and wood |
| What is convection? | thermal energy carried by a fluid from one place to another |
| What is radiation? | thermal energy that radiates from a source outward. like the SUN |
| Radiant energy can transfer what between two objects that are NOT in contact? | Thermal Energy |
| Thermal energy needs what to move? | Matter |
| Insulators | materials that resist the flow of energy. ex: Styrofoam, glass, gases, and a vacuum |
| What is Heat capacity | relationship between thermal energy absorbed and temperature changed because of it |
| Specific heat formula | Q=mcT |
| Latent Heat of fusion is what? | during a melting or freezing period, it is the amount of thermal energy exchanged per gram of material. |
| What is Latent heat of vaporization? | amount of heat it takes to change a liquid into a gas. |
| Freezing | substance changes from liquid to solid |
| Melting | substance changes from solid to liquid |
| condensation | substance changes from gas to liquid |
| vaporization | substance changes from liquid to gas |
| sublimation | substance change from solid to gas *never going through a liquid state |
| deposition | substance changes from gas to solid *Never going through a liquid state |
| Triple point | Temp and pressure where solids, liquids, and gases live simultaneously |
| critical point | temp above which a substance is a gas regardless of pressure |
| freezing point temp where solids and liquids are in equilibrium | freezing point |
| boiling point | temp at which vapor pressure of liquid is equal the pressure of liquid |
| Anything past what point is a gas? | The critical point |
