Explain the thermal properties of water
Zinaida [17]

Answer:

A glance of earth taken from space will depict it blue. This blue colour is actually water, the major part of the earth is covered with water. We need water for almost everything, for example- drinking, bathing, cooking etc and therefore we should know about the properties of water. 65 % human body is composed of water. Water is essential for the survival of life on earth. Water is distributed unevenly on the earth’s surface. It forms a major solvent and dissolves almost every polar solute. So let us have a look at its properties.

Physical properties of water : Water is a colourless and tasteless liquid. The molecules of water have extensive hydrogen bonds resulting in unusual properties in the condensed form. This also leads to high melting and boiling points. As compared to other liquids, water has a higher specific heat, thermal conductivity, surface tension, dipole moment etc. These properties form the reason for its significance in the biosphere. Water is an excellent solvent and therefore it helps in the transportation of ions and molecules required for metabolism. It has a high latent heat of vaporization which helps in the regulation of body temperature

Chemical properties of water: Amphoteric nature:

Water can act as both acid and base, which means that it is amphoteric in nature.

Example:

Acidic Behaviour: H2O(l)+NH3(aq) ⇌ H3O+(aq)+NH+4(aq)

Basic Behavior: H2O(l)+H2S(aq) ⇌ H3O+(aq)+HS−(aq)

Redox reactions:

Electropositive elements reduce water to hydrogen molecule. Thus water is a great source of hydrogen. Let us see an example in this case:

2H2O(l)+2Na(s)→2NaOH(aq)+H2(g)

During the process of photosynthesis, water is oxidized to O2. As water can be oxidized and reduced, it is very useful in redox reactions.

Hydrolysis reaction

Water has a very strong hydrating tendency due to its dielectric constant. It dissolves many ionic compounds. Some covalent and ionic compounds can be hydrolyzed in water.

charle [14.2K]

Halophilic bacteria possess a pigment related to the plant's chlorophyll.

<h3>Halophilic bacteria</h3>

They are bacteria that live in high salt environments. They have a certain feature that enables them to pump out salts in order to maintain normal osmotic conditions in their bodies.

Halophilic bacteria are equipped with bacteriorhodopsin and halorhodopsin. These enable them to photosynthesize like plants. and generate the much-needed ATP for pumping out salts.

Marysya12 [62]
The above statement is true.
The operation of nuclear power plants in the United States is closely monitored and regulated. The NRC or Nuclear regulatory commission is the body that is tasked to monitor and regulate the construction and operation of nuclear power plants. Nuclear power plants use the heat generated from nuclear fission in a contained environment to convert water to steam, which powers generate to produce electricity.

Individuals can control their use of water. Governments can help conserve water by encouraging farmers to plant climate-resistant crops that require less water. Switching to newer alternative energy technologies can reduce water used in fossil fuel and nuclear power plants for cooling.
