Mrs. Buchanan - Energy 2 - Transformations and Heat Transfer
| Question | Answer |
|---|---|
| The law that states that energy can not be created or destroyed is | the law of conservation of energy |
| When energy changes from one form into another it is called a | transformation |
| Which type of energy is always released during a transformation | thermal energy |
| Thermal energy is most often transferred between two solids by which process? | conduction |
| Thermal energy is transferred between fluids by which process? | convection |
| In which direction do does thermal energy flow? | from warmer to cooler areas |
| A generator converts kinetic energy into which form of energy? | electrical |
| A photovoltaic converts which form of energy into electrical? | radiant |
| Friction lowers the efficiency of transformations and produces which form of energy? | thermal |
| A motor transforms electrical energy into which form of energy | kinetic |
| Which type of heat movement occurs through electromagnetic waves? | radiation |
| Which type of heat movement occurs when a bulk of particles move due to a change in their density. | convection |
| Which type of heat movement does not require matter (particles) in which to travel? | radiation |
| A system that produces very little non-useful thermal energy is said to be what? | Energy efficient |
| What happens to the density of particles when thermal energy in a fluid increases? | the density decreases |
| Which direction do particles move when density of a fluid decreases | upward |
