# How Do You Calculate The Energy Of An Explosion?

## How much energy is in an explosion?

One of the most popular explosive compounds is TNT (trinitrotoluene).

The energy released in an explosion of 1 gram of TNT is approximately 4000 Joules.

It is common to measure the power of an explosion by asking how much TNT would be needed to produce an explosion as powerful..

## How are explosions measured?

Explosions are measured in terms of how much TNT (or trinitrotoluene) you would need to create an explosion of equivalent size. … For the sake of measuring explosions, scientists use a constant 4184 Joules per gram to represent that range.

## How big is a kiloton explosion?

… atomic bombs is measured in kilotons, each unit of which equals the explosive force of 1,000 tons of TNT. The explosive power of hydrogen bombs, by contrast, is frequently expressed in megatons, each unit of which equals the explosive force of 1,000,000 tons of TNT.

## How much energy does a nuke release?

Thus, a 1 kiloton nuclear weapon is one which produces the same amount of energy in an explosion as does 1 kiloton (1,000 tons) of TNT. Similarly, a 1 megaton weapon would have the energy equivalent of 1 million tons of TNT. One megaton is equivalent to 4.18 x 1015 joules.

## What is the most powerful chemical explosive?

octanitrocubaneThe R.E. factor of octanitrocubane is 2.38, making it the most effective chemical explosive known.

## What are 2 types of high explosives?

Detonating explosives, such as TNT and dynamite, are characterized by extremely rapid decomposition and development of high pressure, whereas deflagrating explosives, such as black and smokeless powders, involve merely fast burning and produce relatively low pressures.

## What is the most explosive fuel?

One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.

## How big is a mega ton?

1,000,000 tonswords kiloton (1,000 tons) and megaton (1,000,000 tons) to describe their blast energy in equivalent weights of the conventional chemical explosive TNT.

## How much damage can 1 kg of TNT do?

Under controlled conditions one kilogram of TNT can destroy (or even obliterate) a small vehicle. The approximate radiant heat energy released during 3-phase, 600 V, 100 kA arcing fault in a 0.5 m × 0.5 m × 0.5 m (20 in × 20 in × 20 in) compartment within a 1-second period.

## What form of energy is an explosion?

Explosions occur when energy is transformed from one kind e.g. chemical potential energy to another e.g. heat energy or kinetic energy extremely quickly. So, like in inelastic collisions, total kinetic energy is not conserved in explosions.

## What is a high explosive?

High explosives consist of materials that typically combine the reacting elements in the same molecule. This allows them to react much faster, and they “detonate.” Detonation involves supersonic shock waves that pass through the material, causing chemistry that happens quite a bit faster than burning.

## What’s the biggest explosion ever?

The largest accidental non-nuclear explosion in history occurred in Halifax, Nova Scotia, in 1917, when two ships (one carrying explosives) collided. That was nearly 3 kilotons of TNT equivalent, so again Beirut was around a third this size, give or take.

## What is c4 made of?

C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical. C-4 has a texture similar to modelling clay and can be molded into any desired shape.

## How much TNT is in a grenade?

The original Mk 2 grenade had a 3⁄8-inch (9.5 mm) threaded plug in its base, which covered the opening used to place the explosive filling, either 1.85 oz (52 g) of TNT, 2.33 oz (66 g) of Trojan explosive (a mixture of 40% nitrostarch, ammonium nitrate, and sodium nitrate), 1.85 oz (52 g) of a 50/50 amatol/nitrostarch …

## How do you calculate the energy released in an explosion?

The total amount of energy released in the reaction is called the heat of explosion. It can be calculated by comparing the heats of formation before and after the reaction DE = DEf(reactants) – DEf (products).

## What are the 3 categories of high explosives?

High explosives are divided into three main categories, Primary (or Initiating) High Explosives, Secondary High Explosives, Boosters and Secondary High Explosives, Main Charge. As with many of the terms associated with explosions, there is also other terms that describe combustion explosions, “Deflagration Explosion”.

## What is considered a high explosive?

High explosives (HE) are explosive materials that detonate, meaning that the explosive shock front passes through the material at a supersonic speed. High explosives detonate with explosive velocity of about 3–9 kilometres per second (9,800–29,500 ft/s).

## What are the 5 C’s of IED?

(1) IED’s Found Before Detonation – a simple set of guidelines that you should use when you encounter a suspected IED are the five “Cs”. These are Confirm, Clear, Call, Cordon, and Control.
