What is one operational advantage of using steam in heating systems?

Using steam in heating systems offers a significant operational advantage by being able to carry large amounts of energy over long distances. Steam is an effective medium for transferring heat because it can hold a high amount of thermal energy despite being relatively light and occupying less volume than many liquids. This characteristic allows steam to efficiently distribute heat to various locations within a facility or between buildings without requiring extensive piping or complex infrastructure.

When steam travels through pipes, it can remain at a high temperature while cooling down slowly, making it suitable for maintaining consistent temperatures over larger areas. This ability enhances the system's overall efficiency and reduces heat loss, which is crucial for effective heating systems in industrial and commercial settings.

The other choices do not capture the primary benefit of steam regarding energy transfer over distance, leading to their lesser relevance in this context.
