As the temperature rises the kinetic energy of the molecules increases as they begin to vibrate faster. Some of this energy is used to increase the spacing between individual molecules leading to expansion of material.

Thanks alot!, yu really cleared this 4 me. :D
And, if we have a converging lens, when will it form a magnified, virtual image? and when will it form a real, upside-down image?
holtadit:
magnified, virtual = object is closer to the lens than the focal length.
real, upside down = every other position except the one above.
Hesham Mhd:
Really Thanks, yu've got some reputation added :D
