BOMA – HVAC QUESTIONS AND ANSWERS 100% PASS Two basic categories of chillers are the compression cycle and absorption The five requirements for comfort are proper temperature, humidity, filtration, and ventilation circulation The primary function of an expansion device is to produce a reduction in the pressure on the liquid refrigerant, regulate the flow of refrigerant into the evaporator, lower the boiling point of the refrigerant far enough below the temperature of the load to g...

**NOT A SUMMARY, THIS IS IN COMPLETE DETAIL** I attained 99 in Combined Science solely through this self made resource of mine. I have painstakingly gathered information from every EDEXCEL specific resource I could lay my hands on (including seneca, pmt, savemyexams, lit every single video on each topic i could find and the EDEXCEL textbook itself) in order to create this incredibly precise document. It meets every single specification point in meticulous detail, including diagrams and lengthy ...

Bonds within a molecule are called intra-molecular bonds. Non-polar (type) compounds are insoluble in water. intra-molecular Correct! Non-polar Correct! Question 2 10 / 10 pts Fill in the blanks: Pentane is insoluble in water because it is a/an nonpolar (type) compound. Ethyl alcohol has a boiling point of 76.4 C and n-propyl chloride has a lower boiling point of 46.3 C because the Hydrogen bonds holding ethyl alcohol together are stronger than the nonpolar bonds which hold n-propyl chl...
