  1. At boiling point and melting point, there is no change in temperature.  There is only phase change from solid to liquid during melting and liquid to gas during boiling. So at this time specific heat of water becomes infinite. 

  2. At dawn and dusk, large amount of blue and violet light(shorter wavelength) has been scattered so, the light that is recieved by an observer is mostly of a longer wavelength and therefore appears to be red.

  3. According to my research, in Kathmandu, Global College, Prasadi, KMC, and CCRC are better than others, I think.

    But which you choose or which is best for you depends on your findings and if you suits to that environment or not.

  4. No, we cannot determine the exact spin of an electron because we cant really isolate or separate an electron to study it. We can only study its effects.

    Each orbital can have 2 electrons. If we talk about the p shell, it has three orbitals, Px, Py and Pz. Each of these orbitals contain two electrons making 6 electrons in p shell. Among these two electrons, one spins in clockwise direction whereas another one spins in anti clockwise direction. 

    But we cannot determine the exact spin so in theory like valence bond theory if there is only one electron in an orbital we assume it in clockwise direction (by giving an arrow pointing upwards)
