Ionisation:
If the amount of external energy is large enough the valence electron can gain sufficient kinetic energy (energy of movement) to be removed completely from its atomic orbit and may not be replaced by another accelerated electron. This process is known as ionisation, since an atom which now contains one more proton than can be neutralised by the remaining electrons is a positive ion. Gas-filled devices such as Neon tubes make use of this process. In a solid where atoms are close together, simple ionisation does not occur as with individual items.
Defects of Vision Long Sightened When a person can see far objects clearly but cannot see near object clearly then this defect of vision is called as long sightedness.
Magnifying Glass: A biconvex lens of short focal length and low power which forms a virtual and magnified image of an object placed with its focal length is known as magnifying
Two moles of an ideal gas expands reversibly and isothermally to ten times its volume at 25°C. Evaluate the change in entropy during the process. ( R = 8.314 JK -1 mol -1 )
Magnetic thermometer
The energy possessed by a object by virtue of its motion is known as kinetic energy (KE). The KE of a moving body is similar to the amount of work that must be given to bring a
What are the advantages of fibers optics? Glass fiber optics are extremely resilient and ideally fine for working in places where the actual conductor will tend to extreme temp
Is a sewing needle magnetic or non magnetic? Answer:- When you purchase it in the store it isn't magnetized but if you rub it with a magnet it becomes magnetic.
Que: Consider two identical tiny metal balls one having a charge of +1 micro-coulombs and the other having a charge of +3 micro-coulombs. The balls are separated from each one
Production of a magnet: Magnets can be produced in a variety of ways, generally the method used is determined by the type of magnet required. Using the stroke method
