What could happened to heat capacity of solid material if Plank's constant value could be 10 times greater. If Some one knows please help me.

It is always a confusing issue when people want to change a dimensionfull constant, because it is left unspecified what is supposed to vary and what not. It comes more often up with "changing the speed of light" but changing Planck's constant is similar. In the simplest case, you've just re-defined the unit system, and the physics remains the same.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
