Explanation:
The maximum temperature to be carried on a low-pressure hot water boiler is: a) 212 degrees Fahrenheit b) 250 degrees Fahrenheit c) 350 degrees Fahrenheit d) 500 degrees Fahrenheit. The correct choice is b) 250 degrees Fahrenheit. This is because the temperature in a low-pressure boiler does not typically exceed 250 degrees Fahrenheit. This is also reflected in practical applications such as steam engines, which utilize steam up to 450°C (842°F). However, please note that these are general guidelines and the actual maximum temperature may vary depending on the specific design and safety features of the boiler.
