What are typical applications of steam in mechanical systems?

Steam plays a crucial role in various mechanical systems, making it essential in many industrial applications. This option highlights the primary uses of steam, which include power generation, heating, and manufacturing processes.

In power generation, steam is utilized in turbines to convert thermal energy into mechanical energy, driving electricity production in power plants. The process involves heating water in boilers to create steam, which then expands and drives turbine blades connected to generators.

Heating is another significant application of steam. It can efficiently transfer energy to heat buildings, process materials in industries, or even in food preparation. For example, steam heating systems are widely used in hospitals and hotels for comfortable heating and hot water supply.

Manufacturing processes also heavily rely on steam. Industries utilize steam for purposes such as sterilization, drying, and cleaning equipment. Steam's ability to transfer heat and energy makes it especially valuable in processes that require consistent and high temperatures.

Other options present activities that typically do not involve steam directly or primarily, such as fertilization and cooling processes or functions related to water purification and lubrication, which lean more toward liquid applications rather than steam. Therefore, focusing on power generation, heating, and manufacturing effectively captures the essence of steam's role in mechanical systems.
