Explosion

An explosion is a rapid increase in volume and release of energy in an extreme manner, usually with the generation of high temperatures and the release of gases. Supersonic explosions created by high explosives are known as detonations and travel via supersonic shock waves. Subsonic explosions are created by low explosives through a slower burning process known as deflagration. When caused by a man-made device such as an exploding rocket or firework, the audible component of an explosion is referred to as its "report" (which can also be used as a verb, e.g., "the rocket reported loudly upon impact".)

Causes

Natural

Explosions can occur in nature. Most natural explosions arise from volcanic processes of various sorts. Explosive volcanic eruptions occur when magma rising from below has much dissolved gas in it; the reduction of pressure as the magma rises causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events and in phenomena such as hydrothermal explosions (also due to volcanic processes). Explosions can also occur outside of Earth in the universe in events such as supernova. Explosions frequently occur during bushfires in eucalyptus forests where the volatile oils in the tree tops suddenly combust.

Explosion! Museum of Naval Firepower

Explosion! is the Museum of Naval Firepower situated in the former Royal Naval Armaments Depot at Priddy's Hard, in Gosport, Hampshire, England. It now forms part of the National Museum of the Royal Navy.

The Museum includes a wide variety of exhibits ranging from the 18th Century to the present day. These range in size from small arms, to missiles and missile launching systems, as well as complete gun turrets. Exhibits range from the Victorian RBL 20 pounder Armstrong gun through to the Second World War QF 4 inch Mk XVI naval gun. Post-war missile systems include the Exocet missile and launcher and Sea Dart missile. Modern weapons are represented in the Sea Wolf missile system and 4.5 inch Mark 8 naval gun.

The weapons cover all aspects of Naval warfare from surface to surface, air to surface, surface to air and sub-surface weapons systems, including mines and torpedoes.

The museum has a waterside coffee shop which looks out on to the original 18th-century camber dock.
