Energy Transfer
Heat and Sound Energy
| Question | Answer |
|---|---|
| pitch | How high or low a sound sounds to us. |
| frequency | The size of a wavelength. |
| loudness | How loud a sound sounds to us. |
| amplitude | How compressed molecules are |
| compression | Where molecules are compressed due to the transfer of energy. |
| rarefaction | Where molecules are spread out due to the transferring of energy |
| insulator | prevents easy transfer of energy |
| conductor | allows energy to easily transfer |
| medium | anything made up of molecules that transfers energy |
| Longitudinal Wave | How sound transfers by pushing molecules together |
| Thermal Energy | Heat energy carried by the movement of molecules |
| Temperature | measurement of the speed of of molecular movement |
| Mechanical Energy | the total amount of kinetic and potential energy in a system |
| Kinetic Energy | The energy of motion |
| Density | How tightly molecules are packed |
| Equilibrium | The balance between two forces, they become equal. |
| Conduction | Heat transfers molecule by molecule: solids |
| Convection | Hot molecules rise, cool molecules sink. liquids and solids |
| Radiation | Light transmits heat, no molecules needed for transfer |
