What type of energy is primarily possessed by steam before it enters a turbine? 

Explanation:

Energy Possessed by Steam Before Entering a Turbine

• Before steam enters a turbine, it primarily possesses thermal energy.
• Thermal energy is the internal energy of a system due to the kinetic energy of its molecules.
• In the context of steam, this energy is manifested as the high temperature and pressure of the steam generated in a boiler.
• In a typical power plant, water is heated in a boiler to produce steam.
• This steam is then directed to a turbine. The high-pressure, high-temperature steam contains significant thermal energy.
• As the steam expands through the turbine, this thermal energy is converted into mechanical energy, which in turn drives an electrical generator to produce electricity.
