Work function is the maximum energy required by the fastest electron at 0 K to escape from the metal surface.

[A]. True
[B]. False

Answer: Option B

Explanation:

Work function is the minimum energy required by the fastest electron at 0 K to escape from the metal surface.

May I know the correct statement, I think it is at some temperature instead of zero K.

Gnena Sai said: (Dec 12, 2014)  
I want more explanation regarding to it.

Vishwaas said: (Dec 22, 2014)  
Work function always minimum, because it takes less energy to move conduction band to valance band.

Please explain the above statement.

Priyesh said: (Mar 22, 2015)  
Please explain it with details.

Work function is the minimum energy required by an electron to escape from a metal surface at 0 temperature or at a given temperature electron escapes at work function equal to applied energy plus equivalent energy of temperature.

I also required more information for this.

Work function is the minimum energy required to escape the electrons form the metal surface in absolute temperature.

Kundan said: (Oct 1, 2015)  
I think at 0 k temperature most of electrons free to move, so Work function is the minimum energy required to escape the electrons.

Need more information about it. Please explain.

I think, It should be true.
