TEST YOUR ICY INTELLECT
QUESTIONS FROM THE ICE BUCKET

  • Both temperatures are equal. The Celsius and Fahrenheit scales meet at -40 degrees; they are the exact same temperature because that is the precise point where both scales intersect.

  • The fastest ice on Earth can be found at the Utah Olympic Oval in Kearns, UT, at an elevation of 4,528 feet. Every current speed skating world record has been set on this ice, making it unmatched anywhere else on the planet.

  • It takes 1 BTU to raise the temperature of one pound of water by 1°F. A BTU (British Thermal Unit).

    This measurement is commonly used in the heating and cooling industries to quantify the energy needed to heat or cool substances, particularly water.

  • The three primary methods of heat transfer are:

    • conduction

    • convection

    • radiation

  • The first successful demonstration of refrigeration using compressed ammonia was in 1856 by Australian inventor James Harrison.

  • 10 PSIG.

    At standard atmospheric conditions, 0 PSIG = 14.7 PSIA (at sea level). So, 10 PSIG = 24.7 PSIA (10+14.7). 10 PSIA is essentially a vacuum. So, 10 PSIG is greater.

  • None! Ammonia Refrigeration is exempt, but other types of refrigeration require EPA 608 Type II.

  • A) Each plant has its own (SOP) for required PPE and safety measures
    B) Ammonia exposure risks vary depending on system design and facility layout
    C) Proper safety compliance protects workers and ensures regulatory adherence
    »D) All of the above!

  • Induced Draft Condenser.

  • A) To condense refrigerant vapor into a liquid
    B) To evaporate refrigerant liquid into a vapor
    »C) To compress refrigerant vapor, raising its temperature and pressure
    D) To regulate refrigerant flow

  • A) To detect refrigerant leaks
    »B) To identify potential mechanical failures before they occur
    C) To optimize compressor performance
    D) To calibrate refrigerant sensors
