Hydrogen bonds give water which of the following properties? 1. high pH low pH the ability to resist temperature changes 2. the
Furkat [3]

Answer:

3. into ice, which is denser than liquid water.

Explanation:

Water molecules are held together by hydrogen bonds. The bonding is usually between the hydrogen atoms of one water molecules, and oxygen atom of neighboring  water molecules. Structurally,  both oxygen and  hydrogen atoms  pulls the electon towards themselves.Thus both atoms share   electron by covalent bonding.

However, because oxygen  has a strong positively charged nucleus it pulls the electron more to itself than oxygen. Thus oxygen is partially negative and oxygen is partially positive. This interactions take place among  all the oxygen and hydrogen atoms in water molecules. . The unequal charge distributions is called dipole and the attraction between oxygen and hydrogen is called  hydrogen bonding .

The  orientation of hydrogen and oxygen molecules from dipole -dipole  interactions of hydrogen bonding makes the  oxygen and hydrogen atoms in ice to be pushed apart well spaced out in ice, making them less dense than liquid  water  where they were aggregated.  Thus from the question option C is correct.

What is creative electrical energy is converted to mechanical energy
hammer [34]

<em>Energy transformation</em>, also known as <em>energy conversion</em>, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work (Ex: Moving a heavy object from one place to another) On top of that, being convertible, according to the law of conservation of energy, energy is transferable to a different location or object, but it CANNOT be created or destroyed.

When it comes to transforming electrical energy to mechanical energy, A generator converts mechanical energy into electrical energy, while a motor does the opposite. A motor converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.

P.S - After doing some searching, I have found something that should help you, if what I said is confusing or not helpful to you at all. This website has helped me on many occasions and is a very helpful and valuable tool.
