Answer:
Gaseous nitrogen has unique chemical and physical properties that make it suitable for use in food processing. Nitrogen is inert which means it will not react with prepared food materials, which can alter their aromas or flavors. Also, gaseous nitrogen will effectively displace oxygen minimizing oxidation and the growth of microorganisms that cause foods to lose their freshness and deteriorate faster.

Compound is a group of same molecules, Element is a group of same atoms and mixture is combination of two or more pure substances.
What are Molecules ?
Molecules are the combination of two or more different atoms combine in a fixed ratio.
Molecules can be independently founded.
Atoms are always founded in combined state and does not occurs independently except rare earth elements which belongs to 18th group of periodic table.
Chemicals are taken in compound state But they undergo chemical reaction individually in molecular level.
Hence, Compound is a group of same molecules, Element is a group of same atoms and mixture is combination of two or more pure substances.

The correct answer is; Water flowing downstream is held up in a reservoir behind a dam. Some water moves down channels through turbines connected to generators which produce electricity.
Further Explanation:
Hydroelectric power is being used more in recent times than in the past. Hydroelectric power is a more cleaner energy source than the coal plants that produce electricity.
Hydroelectric power plants are built within a dam system and uses the water as source of energy. The water goes into channels created that hits the turbines, the turbines are then moved around by the water and these are connected to the large generators and this produces electric. There are many new hydroelectric plants being built. One of the newest hydroelectric power plants is located in Pella, Iowa.
