5 using heat to stay warm and do work

  1. 1. Using heat to stay warm and do work
  2. 2. <ul><li>Radiator- a device with a large surface area designed to heat the air near it by conduction. </li></ul><ul><li>Solar energy- energy from the sun. Free energy!!! </li></ul><ul><li>There are 2 types of solar heating. </li></ul>
  3. 3. <ul><li>1. Passive Solar Heating- Radiant energy is absorb during the day then converted to thermal energy (heat) to use at night. </li></ul>
  4. 4. <ul><li>2. Active Solar Heating- Radiant energy is absorbed and immediately used to heat water and air. </li></ul><ul><li>-Uses solar collectors. </li></ul>
  5. 5. <ul><li>Heat engines- devices that convert thermal energy into mechanical energy. </li></ul>
  6. 6. <ul><li>Internal combustion engine- </li></ul><ul><li>-Fuel burns inside the engine in cylinders. </li></ul><ul><li>Ex: Engine in cars and trucks </li></ul>
  7. 7. <ul><li>External combustion engine- fuel is burned outside the engine. </li></ul><ul><li>Ex: Old-fashioned engines in steam locomotives. </li></ul>
  8. 8. <ul><li>Heat movers- a device that removes thermal energy from one location and transfers it to another location at a different temperature. </li></ul><ul><li>Ex: Refrigerator </li></ul>
