    • Question
    • Answer
    • Side 3
    • In what forms is water a fluid? give 3
    • tap water, water vapor, steam
    • In what form is water not a fluid give 2
    • snow and ice
    • 3 examples of a method of heat transfer?
    • conduction, radiation, convection
    • which kind of material would reflect radiant energy?
    • light colored materials
    • What is an example of a heat mover?
    • refrigerator
    • OTEC
    • Ocean thermal lenergy conversion
    • 1 example of a method that is NOT a heat transfer
    • insulation
    • 1 example of a poor thermal insulator
    • aluminum
    • Waste gases are removed during what of a four-stroke engine?
    • exhaust strjoke
    • What is the main difference between electrical and fored-air heating systems?
    • electrical systems have no furnaces and no fuel is burned. forced air systems use fuel-burning furnaces
    • Heat can move easily through a good thermal
    • conductor
    • What changes thermal energy into mechanical energy?
    • heat engine
    • what are usually the best conductors of heat
    • metals
    • acting solar heating
    • collecting the sun's energy with solar panels, heating water with that energy and storing the heated water to use the energy later.
    • in solar heating systems, radiant energy from the sun is converted into?
    • thermal energy
    • what are important considerations when selecting insulation for a house?
    • R-value
      location
      climate
    • how does conduction differ from convection?
    • in conduction, particles remain in place, in convection, fluid particles move from place to place
    • what is the most important way thermal energy is trasferred in fluids?
    • convection
    • What does no require the presence of particles of matter?
    • radiation
    • insulator
    • a device that does not allow heat or electrons to move through it easily
    • conduction
    • The transfer of energy through matter in which energy moves from particle to particle, easier in solids
    • combustion
    • rapid burning
    • In order for radiant energy to change to thermal energy, it must be?
    • absorbed
    • How is energy transferred?
    • particles moving at different speeds bump into each other
    • convection
    • transfer of energy by bulk movement of matter in which particles move from place to place in a fluid, carrying the energy with them.
    • fluid
    • any liquid that flows liquids and gasses are fluid
    • solar energy
    • enegy from the sun
      FREE- converted to thermal energy to heat buildings
    • heat mover
      example
    • device that transfers thermal energy fro one place to another
      refrigerator, air conditioner
    • external combustion engine
      give example
    • engine in which fuel is burned outside the engine.
      old fashioned locomotive
    • heat engine
      example
    • device that converts themal energy into mechanical energy. car engine
    • internal combustion engine
      example
    • device uin which fuel is burned inside the engine (cylinders)
      car engine
    • solar collector
    • device that absorbs radiant energy from the sun and converts it to thermal energy to heat buildings
    • radiator
    • device with large surface area that transfers heat to surroung air by conduction
    • insulator
    • a device that does not allow heat or electrons to move through it easily
    • radiation
    • energy transfer by electromagnetic waves
    • ocean thermal
    • process that uses difference in water temperatures to operate a heat engine
    • combustion
    • rapid burning
    • Where does conduction take place
    • solids, liqids and gases
