Planck states that all perfect crystalline system have the same entropy in limit T approaches zero,so we can put the entropy equal zero.Can we demonstrate that or is it only a presumption?
Yes in general, but not for a perfect crystal.fxdung said:Can ground state degenerate,so that Omega_0 greater than 1?
What “complex structure” are you talking about? A perfect crystal has only one ground state, is your "complex structure" referring to something other than the state, if so what?fxdung said:Why in perfect crytal there is a unique ground state if we consider the complex structure of each vertex of lattice?
At zero degrees Kelvin, also known as absolute zero, the entropy of a system is equal to zero. This means that there is no disorder or randomness in the system, and all particles are in their lowest possible energy state.
No, according to the third law of thermodynamics, the entropy of a perfect crystal at absolute zero is zero and cannot decrease any further. This is because all particles are in their lowest energy state and cannot become more ordered.
At absolute zero, there is no thermal energy or movement of particles, so the temperature is also zero. This means that the change in entropy is directly proportional to the change in temperature, and at absolute zero, the change in entropy is zero.
Zero degrees Kelvin is considered the lowest possible temperature in the universe and is used as a reference point for measuring temperature in the Kelvin scale. It also serves as a reference point for the third law of thermodynamics, which states that the entropy of a perfect crystal at absolute zero is zero.
No, entropy is a measure of the disorder or randomness in a system, and at absolute zero, there is no disorder or randomness, so the entropy is zero. It cannot be negative as it is a measure of the degree of randomness, not the lack of it.
