Human Body Quizzes & Trivia

How well do you know about thermal comfort? Thermal comfort is the ability of a person’s mind to be at peace when it comes to the thermal temperature. The quiz below is perfect for helping you see just how well you can achieve this condition, and it’s important to the body as a whole. Do take the quiz and get to find out!

Questions and Answers
  • 1. 
    [Blank] is a subjective state of satisfaction that varies with the individual and a number of circumstantial factors. 
  • 2. 
    The human being is a [Blank] that burns food as fuel and generates heat as a byproduct. Exhaling warm moist air from the lungs loses some heat, but most of the body’s flow is through the skin.
  • 3. 
    The [Blank] regulates the heat flow by controlling the amount of blood flowing through it.
  • 4. 
    The primary way that the human body gains heat is through [Blank]
  • 5. 
    Heat is transported around the body by the[Blank].
  • 6. 
    For the proper functioning of the organs of the body, and particularly for that of the brain, the temperature of the internal organs must be maintained constant, at around [Blank]°C.
  • 7. 
    If it rises above [Blank] °C or falls below [Blank]°C, death is imminent.
  • 8. 
    The controlling mechanism for this is the [Blank]
  • 9. 
    If Brain temperature falls outside these very close limits, the body will react physiologically to restore heat balance.
    • A. 


    • B. 


  • 10. 
    To create thermal comfort, we must understand not only the heat Dissipation mechanisms of the human body but also the four environmental conditions that allow the heat to be lost:
    • A. 


    • B. 

      Metabolic rate

    • C. 

      Air Velocity

    • D. 


    • E. 

      State of health

    • F. 

      Mean radiant temperature (MRT)

    • G. 


    • H. 

      Air temperature

  • 11. 
    The [Blank] is the heat transfer of heated or cooled mass (the trasfer of of heat between a surface and moving fluid (air or liquid). = [Blank] by movement of molecules from one region of fluid to another region 
  • 12. 
    The [Blank] will determine the rate at which heat is lost to the air.
  • 13. 
    Internal Comfort temp: [Blank] - [Blank] ˚C
  • 14. 
    Humidity: [Blank]
  • 15. 
    Air movement affects the heat-loss rate by both and
    • A. 


    • B. 


    • C. 


    • D. 

      Comfort wind

  • 16. 
    [Blank] is simply the area-weighted mean temperature of all the objects surrounding the simply the area-weighted mean temperature of all the objects surrounding the body. 
  • 17. 
    [Blank] is a unit of measurement used to define power  ( power = energy consumed over a period of time)
  • 18. 
    Comfort wind less than [Blank] %. Example: [Blank]c with [Blank]% humidity is acceptable and [Blank]% wind.
  • 19. 
    The [Blank] chart is a powerful tool for understanding how the combination of temperature and humidity affect comfort.
  • 20. 
    One measure of the effect of moisture in an air-vapor mixture is [Blank]. It is measured using a thermometer with a wetted bulb moving rapidly through the air in order to promote evaporation.
  • 21. 
    [Blank]is noted as the difference in the temperatures between the wet wick thermometer and the DBT.
  • 22. 
    [Blank] is an expression of the moisture content of a given atmosphere as a percentage of the saturation humidity at the same temperature:
  • 23. 
    [Blank] is the vapor content of air, given in grams of water vapour per kg of air, i.e. g/kg. Air at a given temperature and pressure can support only a certain amount of moisture and no more.
  • 24. 
    The DBT corresponding to this point is referred to as the [Blank] of the original atmosphere. If there is further cooling, the status point will move along the saturation line and condensation will occur.
  • 25. 
    [Blank] (reciprocal of density, in m3/kg) of the air-vapour mixture is indicated by another set of slightly more sloping lines on the psychrometric chart.
