The valence band and conduction band of a solid overlap at low temperature. The solid may be:

In a good conductor,the energy gap between the conduction band and the valence band is:

In semiconductors at room temperature,

This question has Statement $1$ and Statement $2$. Of the four choices given after the Statements,choose the one that best describes the two Statements.
Statement $1$ : $A$ pure semiconductor has a negative temperature coefficient of resistance.
Statement $2$ : On raising the temperature,more charge carriers are released into the conduction band.

At room temperature,in a semiconductor material:

The energy required for an electron to jump the forbidden band for germanium at room temperature is $........... eV$.
