GCAP CERTIFICATION PAPER 2026 FULL
SOLUTION GRADED A+
● 1 Kitchen Match. Answer: The heat released by burning a kitchen
match from end to end is equivalent to 1 BTU.
● NH3 Evaporation. Answer: Evaporating 1 lb of ammonia absorbs 561
BTU of heat, making it effective for cooling.
● NH3 Efficiency vs. Freon. Answer: Ammonia is 7x more efficient than
Freon, reducing energy costs.
● Ammonia Detection. Answer: Humans can smell ammonia at 2-5 ppm.
● PPM Conversion. Answer: 1% = 10,000 ppm.
● 0.5% NH3 (5000 ppm). Answer: This concentration can be lethal
without PPE.
● PEL for NH3. Answer: OSHA's Permissible Exposure Limit (PEL) for
ammonia is 50 ppm.
