Water on earth remains in a constant cycle. It moves from the ocean, seas, rivers, gets evaporated, goes into the atmosphere and again comes back to the earth in the form of rain, snow, hail etc. Snow is always formed in the cold clouds because their temperature is low, generally below freezing point. So [...]

When a stone is thrown in the water say pond, tank etc. you have noticed that many small waves of water are formed which moves away from the point where stone hits the water. These are known as ripples.
Water in liquid state is not fixed sheet so it can easily change the shape. When a [...]

You have always noticed that an egg sinks in the fresh water or plain water while it starts floating in the salt water this because when you add salt to the water you are adding more molecules to the water. Earlier the molecules were apart from each other but now salt molecules have occupied some [...]

Water is the most essential substance required by all humans, plants and animals. We cannot imagine life without water but nowadays water on earth is getting polluted which has become a topic of discussion. Polluted water can badly affect our health and also the animals living underwater because the life on earth is completely dependent [...]

Everything is made up of atoms whether it is natural material or man made material like plastics, synthetic etc. it is the smallest particle in each and every substance. Many atoms combine together to form molecule. A single drop of water has billions of molecules and each molecule of water has two atoms of hydrogen [...]

Airplanes are safer than the automobiles. Chances of dying in a car accident are much more than the chances of dying in a plane crash. It is about one in 11 million in an aircraft while in an automobile the chance of dying is one in 5000 so it is safer to fly in an [...]

Glacial ice appears blue to us because all the colors of the visible spectrum (red, orange, yellow, green, blue, indigo, violet) except blue is absorbed by the ice. This blue color wavelength is transmitted which is responsible to make our eyes see the blue color of glacial ice. For this, the light has to [...]

Without protein our body cannot function properly.
Our body nerves, tissues, bones all are made up of proteins. So proteins become very necessary for them to grow and repair. It also used to produce some hormones and enzymes in our body .proteins are made up of amino acids. Our body produces non essential amino acids and [...]

Oxygen present in water and salt causes corrosion. Salt is hygroscopic in nature and it attracts the water. Water is required for corrosion and salt speeds up the process.
Corrosion is the transfer of electrons from one substance to the other so salt present in water improves the capability of water to carry electron through [...]

You can prepare bath salt on your own instead of buying commercial bath salts which contain chemical. If you store properly the salt which you had prepared can last up to several months.
Things which are required
1) 2 cups of Epsom salt- it contains magnesium sulfate helps to take away acids from the skin and can alleviate [...]

Sea salt is obtained from the North Sea, Mediterranean Sea or the Atlantic Ocean in France’s Brittany coast and also in Maine, Cape Coa, mass in united states of America. Mainly the process involved in harvesting sea salt is evaporation.
On a big scale salt is extracted by using big tanks. Sea water is pushed into [...]

To know about why ice stick to your skin we have to first know about the formation of ice. On the outer level we say that when we cool the water to certain temperature it turns to ice but on molecular basis it is something different.
We know that the water (H2O) is made up of [...]

Forests all around the world are getting destroyed for one or the other reason. In U.S.A one billion acres of land was covered by forests and now only five percent of it is left.
Tropical rain forests are destroying at the rate of 80,000 acres per day. So we have to take steps to preserve the [...]

Fire in the forest is a destructive process. It can occur in both temperate and tropical forests. Fire can be due to the lightening or the carelessness of human beings. Nearly 90 percent of the forest fires are caused because of human beings. Also some fires start in the hot and dry weather usually in [...]

Forests are very important and beneficial for local, national and international levels. We obtain a lot many products from the trees of forests.
WOOD AND ENERGY
It is one of the most important benefits of the forests that we get wood from the trees which are further used in many products used by us like timber wood [...]

In the places where there is too much of snow and ice in the winter on the roads there the highway departments use to sprinkle the salt over the ice to clear the roads. They use salt for this purpose because salt has the tendency to lower the freezing and melting point of water so [...]

We see a particular an object having a particular color. This is because it absorbs all the colors coming towards it in a light spectrum and the color which it reflects it appears of that color. Different objects absorb different wavelengths and the heat energy.
Mostly we have seen that a dark color absorbs more heat [...]

Aeroplanes fly and reach to a height by using two things. One is the Bernoulli’s effect and other is the simple momentum transfer in the flow of air for the lift.
Daniel Bernoulli stated a principle which says that with the increase of speed of fluid the pressure decreases. Here the air over an airplane works [...]

Stain removers and detergents that are used nowadays have enzymes which work to remove the organic stains while bleaching chemicals in stain removers remove the non-organic stains. These enzymes work in a simple way. It breaks the stains so that it will be easier for the enzymes to remove them by water or they are [...]

We know that earth is tilted at a particular angle and also revolves around the sun. Different parts on the earth get more or less amount of the sunrays which cause the seasons and length of days and nights.
This can be easily understood by performing an experiment. Take an apple and pass a stick [...]
