Answer :
Final answer:
A sprinkler system that contains water under pressure in the piping is used in locations where temperatures remain above 32 degrees Fahrenheit to prevent the water from freezing and ensure the system operates effectively. The correct answer is b) 32 degrees Fahrenheit.
Explanation:
The question asks about the type of sprinkler system that contains water under pressure in the piping and is typically used in locations where temperatures remain above a certain threshold to prevent the water from freezing. The correct answer is b) 32 degrees Fahrenheit. This is because water freezes at 32 degrees Fahrenheit, and for a sprinkler system to function effectively, the water in the system must remain in its liquid form to be able to extinguish fires when needed. Therefore, these systems are designed for areas where the temperature does not fall below the freezing point of water to ensure the water remains liquid and can flow when the sprinkler system is activated.
The correct answer is b) 32 degrees Fahrenheit.
