If a hot piece of thick glass is clipped in cold waterit breaks.Give reason?

The edges of the thick glass will cool faster than the center portion since the glass has low thermal conductivity. This produces a thermal gradient in the glass putting the outside edges in a state of tension stress. Glass fails in tension at a low value if any flaw exists on the edge surface.
