Different types of pollution

Today I will write about something that is a very vital issue regarding mother earth. You all know about pollution and pollution effects such as the effect of water pollution are harming not just mother us but directly to human too. But not many of us do anything to control it.

I want to give a start and so I am acknowledging the different types of pollution here itself:

• Air pollution.
• Water pollution.
• Noise pollution.
• Soil pollution.
• Thermal pollution.
I have just given a start; you all acknowledge the causes and start controlling these causes in order to save earth and save human kind.

Do share with me your experiences and suggestions.

Physical properties of Oxygen

Writing educating blogs is really a pleasurable experience. It not just allows me to help you but at the same time it helps me to refresh my own memories. We all are familiar of the gases such as Oxygen, Nitrogen, Carbon di oxide and so on and also we know about their respective physical quantities or properties. Today’s let’s learn the physical properties of oxygen and their physical structure.

The following are the physical properties of oxygen:

• Oxygen is colorless, odorless and tasteless in normal conditions.
• It is heavier than air.
• It is soluble in water.
• It is paramagnetic to nature
• It liquefies to give pale blue liquid.
I am sure you got a quality learning through this writing and I am sure you will post me your feedbacks.

Fish life Cycle

In this post we will learn about fish , and a basic fish life cycle.Fish live their entire life in water.

  

A typical fish life cycle starts with an egg. The egg hatches into what is called a yolk sac fry - a larval stage where the fish has an attached yolk that provides it with nourishment for its first week or two.

The true larval stage begins when the fish has absorbed the yolk and starts feeding for it self.

When the fish gets bigger and looks very much like an adult, it is considered a juvenile.

Once the fish matures and can reproduce and lay eggs, it becomes an adult. 

I guess this post was useful, please send me your suggestions and comments. In the next post we will learn about fish respiratory system in detail.

Types of Enzymes

In this post we will learn about the types of enzymes and their functions.

We have three main categories of enzymes:

1)      Metabolic Enzymes

2)      Digestive Enzymes

3)      Food Enzymes

Metabolic Enzymes: These metabolic enzymes are responsible for the smooth running of the body, tissues and organs. They help us in the overall growth of cells , repair and maintenance of the body’s organs and tissues.

Digestive Enzymes: Digestive enzymes are responsible in the digestion of food and the absorption and delivery of nutrients throughout the body.. Each enzyme is specific to a particular compound which it breaks or synthesizes

Food Enzymes: Food enzymes are derived solely from raw fruits, vegetables, and supplemental sources. Like digestive enzymes, they enable the body to digest the food by breaking down the various nutrients -- proteins, fats, carbohydrates, and vitamins and minerals - into smallest compounds that the body can absorb. They are absolutely essential in maintaining optimal health.

States of Water

There are 3 states of water. They are solid, liquid, and Gas. As we know there are various liquid solutions, which are formed by combining two liquids.

Gas to Liquid:  When the gas changes to liquid , we have a process of condensation. So, in this process gas cools and loses energy. So, the water particles are forced to change the state, from gas to a liquid.

Liquid to Solid: When a liquid changes to solid, the process is called freezing. When the liquid cools below the freezing point and loses energy. Then the particles are forced to change state from liquid to a solid.

Solid to Gas: When a solid changes directly to a gas, the process is names Sublimation.

Liquid to Gas:  This is a process where liquid changes into gas and the process is called evaporation. 

 I hope we have understood the different states of water. for more science help, please look into my other posts on science.

Convex Lenses

In this post we are learning about convex lens.Convex lens is the most commonly-seen type of lens. This type of lens is often used for close examination of small objects, such as rare stamps or coins.

Lens that possesses at least one surface that curves outwards. It causes light to deviate inward, bringing the rays of light to a focus, and is thus called a converging lens. A convex lens is thicker at its centre than at its edges, and is used to correct long-sightedness (hypermetropia).

The distance between the lens and the point at which all the rays of light converge (the focal point) is called the focal length. The centre of the lens is known as the optical centre.

At close distance a convex lens forms a magnified virtual image of an object. At further distances the image formed is real, and it can be focused and projected onto a screen behind the lens. The real image formed is upside down, and it can be smaller than, the same size as, or larger than the object depending upon how far the object is from the lens.

Types of Soil

In this post we will learn about soil and the types of soil .Soil can be defined as a thin layer on the surface of the Earth on which the living beings of the earth survive since it is the layer of materials in which plants have their roots.

Layers of Soil is made up of many things like weathered rock particles and decayed plant and animal matter. It takes a long time for soil formation and more than thousand years for the formation of a thin layer of soil. Since soil is made up of such diverse materials like broken down rock particles and organic material, it can be classified into various types, though based on the size of the particles it contains.

Soil Types

Therefore depending on the size of the particles in the soil, it can be classified into these following types:

• Sandy soil
• Silty soil
• Clay soil
• Loamy Soil
• Peaty Soil
• Chalky Soil 

I hpe this was a good and a useful post.
