Science

B.Sc IT is a program wherein students are trained to perform well in computer applications and Software. And B.Sc CS is a more academic course, and focuses mainly on mathematical and theoretical foundations of computing plus hardware focus.
Among the two, B.Sc IT is designed according to the needs of the IT industry while B.Sc CS enlightens more of theoretical aspects.
Both have their own merits offering challenging jobs in the field of computers. I would suggest you to analyze the various opportunities available and select the right path based on your personal criteria which should include:
*The interest and aptitude towards the subject
*Interest to get a job
*The future Demand for the particular program

The difference between class and object is one of the most common questions, you would like to ask a fresher coming out from college or training institute, but you would be surprised how many beginner Java programmers struggle with this question. Class and Object are two pillars of Object Oriented Programming (OOPS) and a good understanding is a must, but when you ask this question apart from the theoretical and bookish answer that "class is a blueprint and objects are actual things created out of that blueprint", you would hardly get anything substantial. Though that answer is correct and works perfectly, it doesn't differentiate between a programmer, who has just mugged the answer, or the one who truly understand the difference between class and object.

A soap molecule a tadpole-shaped structure, whose ends have different polarities. At one end is the long hydrocarbon chain that is non-polar and hydrophobic, I.e., insoluble in water but oil soluble. At the other end is the short polar carboxylate ion which is hydrophilic I.e., water soluble but insoluble in oil and grease.
When soap is shaken with water it becomes a soap solution that is colloidal in nature. Agitating it tends to concentrate the solution on the surface and causes foaming. This helps the soap molecules make a unimolecular film on the surface of water and to penetrate the fabric. The long non-polar end of a soap molecule that are hydrophobic, gravitate towards and surround the dirt (fat or oil with dust absorbed in it). The short polar end containing the carboxylate ion, face the water away from the dirt. A number of soap molecules surround or encircle dirt and grease in a clustered structure called 'micelles', which encircles such particles and emulsify them.
