  • Q2
    Which type of materials have low thermal conductivity?
    thermal insulators
    non-metals
    thermal conductors
    metals
    60s
  • Q3
    Which of these is NOT one of the three factors that determine the rate of thermal energy transfer through a material?
    starting temperature
    thermal conductivity of material
    thickness of material
    temperature difference
    60s
  • Q4
    Which of these is NOT one of the three factors that affect the rate of heat loss from a building?
    the type of heating used in the building
    thickness of walls and roof
    the temperature difference between the two sides of the wall/roof
    thermal conductivity of walls and roof
    60s
  • Q5
    60s
  • Q6
    What is the name for the electromagnetic radiation that transfers heat?
    thermal radiation
    ultraviolet radiation
    infrared radiation
    microwave radiation
    60s
  • Q7
    What is the relationship between the temperature of an object and its emission of infrared radiation?
    the temperature of an object does not affect how much infrared radiation it emits
    the lower the temperature of an object, the more infrared radiation it emits
    the higher the temperature of an object, the more infrared radiation it emits
    the higher the temperature of an object, the less infrared radiation it emits
    60s
  • Q8
    What can you tell about an object that absorbs and emits infrared radiation at the same rate?
    it is at a constant temperature
    its temperature will be decreasing
    it is a thermal conductor
    its temperature will be increasing
    60s
  • Q9
    Compare the amount of infrared radiation emitted and absorbed by an object that is increasing in temperature.
    more infrared radiation absorbed than emitted
    less infrared radiation absorbed than emitted
    more infrared radiation will be emitted than absorbed
    equal amounts of infrared radiation absorbed and emitted
    60s
  • Q10
    What term is used to describe a theoretical object that absorbs 100% of the radiation that falls on it?
    full efficiency body
    full absorption body
    black mass
    black body
    60s
  • Q11
    Which of these is NOT a greenhouse gas?
    water vapour
    nitrogen
    carbon dioxide
    methane
    60s
  • Q12
    Which of these human activities do NOT increase the levels of greenhouse gases released?
    deforestation
    livestock farming
    burning fossil fuels
    using electric cars
    60s
  • Q13
    What do greenhouse gases do that increases the Earth's temperature?
    they generate infrared radiation which they emit towards the Earth's surface
    they absorb radiation from the Sun then re-emit this radiation towards Earth’s surface
    they absorb the heat emitted from the Earth then re-emit this radiation back towards Earth’s surface
    they absorb the heat from the Earth's surface and the Sun which makes the Earth hotter
    60s
