Answer:

When a metal is heated sufficiently, the thermal energy supplied to the free electrons causes the emission of electrons from the metal surface. This occurs because the thermal energy given to the carrier overcomes the work function of the material. ... As more heat is supplied, more are the number of electrons ejected.
