    One pascal is equivalent to one newton (1 N) of force applied over an area of one meter squared (1 m2). That is, 1 Pa = 1 N · m-2. Reduced to base units in SI, one pascal is one kilogram per meter per second squared; that is, 1 Pa = 1 kg · m-1 · s-2. Pascal is the SI unit of pressure. It is equivalent to pressure exerted when 1 Newton of force is applied over an area of 1 squared meter.

    Sonali Aggarwal 7 years, 5 months ago

    Malleability is the ability of a substance, usually a metal, to be deformed or molded into a different shape. For chemists, the malleability of the metal gives an important means of describing the specific characteristics of a metal and relating it to the arrangement of the atoms within the metal

    Water is a conductor of electricity, so it can easily conduct electric current and cause danger of electric shocks or short-circuits. Therefore, water can not be used to control the fire involving electrical equipment. ... So it does not catch fire. Water is a good conductor of electricity. So when it is used to extinguish fire caused by electricity then it may cause electrocution to the person who are extinguishing the fire. water is a very much good conductor of electricity. so it must never be used to extinguish fire involving electrical equipments.

    CNG is comprised mostly of methane gas which, like gasoline, produces engine power when mixed with air and fed into your engine's combustion chamber. CNG is compressed so that enough fuel can be stored in your vehicle to extend driving range, much like the gasoline tank in vehicles. Combustion of fuels like petroleum causes formation of un-burnt carbon particles along with carbon monoxide gas. These harmful pollutants enter the air and cause respiratory diseases. It is a comparatively cleaner fuel. Therefore, the use of CNG has reduced pollution in our cities.

    Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming. Penicillin was discovered in London in September of 1928. As the story goes, Dr. Alexander Fleming, the bacteriologist on duty at St. Mary's Hospital, returned from a summer vacation in Scotland to find a messy lab bench and a good deal more. People began using it to treat infections in 1942. Fleming's legendary discovery of penicillin occurred in 1928, while he was investigating staphylococcus, a common type of bacteria that causes boils and can also cause disastrous infections in patients with weakened immune systems.

    Friction is of three types:

    1. Static friction: The maximum frictional force present between any two objects when one object just tends to move or slip over the surface of the other object, is called static friction. In case of static friction, the object is actually not moving or sliding over the other object, it only tends to move or slide.
    2. Sliding friction: The frictional force present when one object moves slowly or slides over the surface of another object, is known as sliding friction. Thus sliding friction comes into play when an object is sliding over another object. Since sliding friction is smaller than the static friction, it is easier to keep an object moving which is already in motion than to move the same object from rest. That is why, sliding friction is smaller than the static friction.
    3. Rolling friction: When an object rolls over the surface of another object, the resistance to its motion is called rolling friction. Rolling friction is much less than sliding friction. Heavy machines can easily be moved from one place to another by placing round logs of wood under them and pushing with the force of hands.
