Out of the pan and into the fire: take a quiz on heat and energy!

  1. Heat is a measure of
    1. the rate of conduction in a substance.
    2. the speed at which the molecules are moving.
    3. the frequency of a wave.
    4. the amount of radiation given off by a substance.
  2. Heat can be transferred by
    1. convection.
    2. radiation.
    3. conduction.
    4. All of the above
  3. A metal frying pan is a good conductor of heat because
    1. it prevents food from sticking.
    2. it permits convection.
    3. it transfers heat quickly.
    4. it insulates food from the air.
  4. Microwaves
    1. use nuclear energy to cook food.
    2. heat the food’s outer layer first.
    3. deposit energy directly inside food.
    4. heat up the air around the food.
  5. Convection occurs when
    1. heat circulates in a fluid such as water.
    2. heat is transferred directly between solids.
    3. food is placed in direct contact with heat source.
    4. food is heated by microwaves.
  6. A pan on the stove heats up mainly through
    1. convection.
    2. conduction.
    3. radiation.
    4. microwave energy.
  7. Wavelength is a measure of
    1. the distance between a wave’s highest point and its lowest point.
    2. the distance between two neighboring peaks of a wave.
    3. the distance a wave travels in one second.
    4. the heat given off by a wave.
  8. Which is an example of an inverse relationship?
    1. The lower the temperature, the less time it takes to freeze water.
    2. The more water in the pot, the longer it takes to boil.
    3. As the days grow longer, the nights get shorter.
    4. The higher the pressure, the higher the boiling point of water.
  9. The electromagnetic spectrum is organized by
    1. the year the wave was discovered.
    2. the speed at which the wave travels.
    3. wave temperature.
    4. wavelength.
  10. The frequency of an electromagnetic wave tells
    1. how often a wave peaks in a second.
    2. the distance between the peak and valley of a wave.
    3. how fast the wave travels.
    4. the temperature of the wave.
  11. Which number equals 10³?
    1. 30
    2. 300
    3. 100
    4. 1000
