How does a explosion happen?

The generation of heat in large quantities accompanies most explosive chemical reactions. It is the rapid liberation of heat that causes the gaseous products of most explosive reactions to expand and generate high pressures. This rapid generation of high pressures of the released gas constitutes the explosion.
