| Question | Answer |
|---|---|
| temperature | measures the average kinetic energy of the particles if an object or substance. Measures how fast particles move |
| thermal energy | the sum of all the energies of the molecules of a substance |
| heat | the flow of energy from warmer places to cooler places due to difference in temp. |
| specific heat | the amt of energy needed to raise temperature of 1kg of that substance by 1`C |
| thermal energy equation | Q=cmdeltaT |
| conduction | the transfer of thermal energy through matter by direct contact |
| convection | heat transfer in fluids or heat transfered through currents |
| radiation | the transfer of thermal energy in the form of waves and can happen in a vacuum |
| conductors | materials that allow heat energy to move through them efficiently are called conductors (metals are good at this) |
| insulators | slows down the transfer of energy. materials that don't allow energy to pass through them well, are called _______ |
| therodinamics | the study of the relationships between work, heat, and thermal energy |
| heat engine | a device that converts thermal energy to mechanical energy |
