types of matter


In this blog we are going to discuss about  matter.So do you know What is matter?


Matter is everything that is around us.
Anything that has an existence, due to which one is able to see and feel it directly, is called matter.

Matter can be identified by certain properties or behaviour. 
Balloons, football and orange juice are all examples of matter having certain properties.
Matter is an entity that takes up space and occupies it. The amount of space occupied by any matter is called its volume.
Watch the difference in the levels of the pans of the weighing scale shown here
The inflated balloon has air in it and is therefore heavier than the deflated one.

Air is matter and matter has weight.
Observe that the ice sinks down by the force of the juice that’s being poured.
The force exerted by matter is called its pressure

Matter can be identified by certain properties: -

Matter is anything that
1) Has weight.
2) Occupies space and
3) Exerts pressure.

Now see the given link to know about types of matter.

types of food


In this blog we are going to discuss about types of types of food.Also see the given link types of proteins.
Food gives us everything we need to be healthy and strong.
Food gives us energy to play and work; it builds and repairs our body, and helps us recover from illness.All these functions are performed by the essential nutrients present in food which are: Proteins, carbohydrates, fats, vitamins and minerals. Let us learn about each of these nutrients in detail.
Proteins
Proteins help in building new cells and repairing damaged body parts. So, proteins are aptly called body building nutrients.
Proteins are present in almost all food items. But, foods like milk, cheese, meat, eggs and pulses are very rich in proteins.
Carbohydrates
The energy our body needs to perform various actions comes mainly from carbohydrates. Carbohydrates are called energy giving nutrients.
Carbohydrates are found in the form of sugar and starch. Sugar is a simple form of carbohydrates. It gives us energy instantly. Starch is a complex form of carbohydrates.
Fruits, sugarcane, honey, beetroot, rice, maize, wheat, corn, potato, chocolates, etc. are rich in carbohydrates. 
Fats
Milk, meat, oil, butter, ghee, nuts, etc. are rich in fats.
Fats are also called energy giving nutrients, as they are a source of energy to the body.
Fats provide about twice the energy that can be derived from equal amounts of carbohydrates or proteins.
Vitamins
There are two kinds of vitamins; water soluble vitamins and fat soluble vitamins.
Water soluble vitamins are found in citrus fruits, unpolished cereals, and green vegetables. They are vitamin C and B complex.
Minerals
Minerals include calcium, phosphorus, sodium, potassium, magnesium, iodine, copper, iron, zinc, etc. They are inorganic elements. Plants take in minerals from the soil and store it in the food they prepare. Minerals enter our body through the food we eat. 
Next time we will discuss more about this concept.

types of force

In this blog we are going to discuss about types of force.See the mentioned link before going through the blog define force.
Types of Forces:

Forces are of different types. They are as follows,

Electromagnetic forces - The properties of the electrostatic perforate omnifarious as an backward parcel law directed in the immoderate content was both enchanting and ugly are depends on law of caretaker stance.
Nuclear forces - Nuclear forces is described as interactions that hump square in quantum theories of particle physics.

Normal forces
- The median move is created due to interconnection among the atoms at unplumbed happening.

Receptive displace - An objective accelerating in advertising move, the unbalanced drive activity on the entity equals.

Blimpish forces - Orthodox forces are forces which are victimized to modify drive among the possibility or kinetic forms. This vitality is mainly for mechanical manipulate.

Types of forces playacting on a body:

Symmetrical forces:

       If a come of forces are acting on body and body  not move, then the forces are called as poised forces.

Imbalanced forces:

        If a stage of forces acting on a embody is non-zero, the land of breathe or event of the embody changes, such forces acting on the body are said to be unbalanced forces.

transverse waves

In this blog we are going to discuss about  transverse waves.
Wave is a disorder produced in a substance due to the repeated vibrations of the particles of the transmission, some their reaction orientation.

Waves are generally grouped as: -

1) Longitudinal waves
2)Transverse waves

) Transverse wave
A wave, which propagates in a direction perpendicular to the direction of vibration of the particles of the medium, is called transverse wave.
Electromagnetic waves & vibrations in a string of a violin are transverse in nature.
The elevated portions of the string are called the crests & the depressed portions are called the troughs.
See the given link to know more electromagnetic waves definition.

Air Dirtying

Air pollution is the change or locomote in the compoition of air due the increase of unfavorable or unwanted substances due to the termination of substances equivalent automobile and postindustrial gases and material concern. Opposite sources of air pollution are gas from the automobiles, perfervid of fossil fuels, pollutants from the industries similar the energy plants, fertiliser plants, brace plants, textile industries, etc., extrusive eruptions, gases released due to the anaerobiotic putrefaction of fertilizer wastes, etc. The six principal air pollutants are oxides of element, oxides of cryogen, process gas, hydrocarbons, aerosols, and nonsynthetic and mineral material matters. Subdivision virtually soiling caused to air is it affects all the extant organisms on connective as air is the weighty element which is required for activity.
