question accha hai bro!!! nice

Answer 2

Option D) All of the above​

Electronic contribution of specific heat varies lineraly with temperature.

• The electronic contribution to specific heat is always linear with temperature and is not at all dependent on the size of the system.
• Three-dimensional electron gas, two-dimensional electron gas, and one-dimensional electron gas are the proper responses.
• The electronic specific heat, also known as the electron heat capacity in solid state physics, is the heat capacity of an electron gas. In materials, phonons and free electrons both transmit heat. But in the case of pure metals, the thermal conductivity is mostly influenced by electronic contributions.
• Only in metals does the electronic contribution occur, and it results from changes in the density of states at the Fermi level. For instance, the difference in electronic entropy between two configurations is proportional to both the temperature, T, and the change in the density.
