what happen for metals when increasing the temperature?

Question

anonymous · Answer

The ions vibrate.

anonymous · Answer

in what sense do you want answer????

on heating the particles gain energy and start vibrating more rapidly and with greater amplitude, about thier mean position...
metals expand on heating....
once melting temperature is reached, the  metals liquify and start flowing....

anonymous · Answer

They expand and eventually melt, and then turn to vapor.

anonymous · Answer

when increasing the temperature ,the density of metal is decrease and eventually metal expand

anonymous · Answer

when the temperature of the metal increases, the free electrons present in metals vibrate and these electrons bump with each other and due to the motion of the electrons, the heat and electrical resistance of the metal increases ( refer toFourier's Law of heat conduction).

anonymous · Answer

the conuduvtiviy decreases...as resistance is directly proportional to temperature...the opposite happens in non conductors or semi conductors..in semi conductors the energy gap between the valence band and the conduction band decreases.
