Question

When temperature of a metal increases

a) K.E. of electrons decreases b) K.E. of electrons increases

c) all the electrons are ejected from the atom d) all the atoms are ionised​

Answer 1

Answer:

In a conductor, the charge carriers are electrons. As the temperature is increased, the collisions of these conduction electrons with the fixed ions of the lattice of the metal increases and hence the resistance of the conductor also increases.

Answer 2

Answer:

1)K.E. of electrons decreases.
