Question 1

is the rapid increase in volume and release of energy in an extreme manner.

Answer 1

Explosion

Question 2

It is the result of a rapid expansion of gases, and it may occur from physical or mechanical change.

Answer 2

Explosion

Question 3

It is a sudden, violent change of potential energy to work, which transfers to its surroundings in the form
of a rapidly moving rise in pressure called a ____

Answer 3

blast wave or shock wave

Question 4

produces a strong supersonic pressure wave.

Answer 4

High order explosion

Question 5

It occurs at or near its maximum theoretical detonation velocity.

Answer 5

High order explosion

Question 6

It’s the explosion that occurs when everything
works right.

Answer 6

High order explosion

Question 7

have a subsonic explosion and lack the high order explosive blast wave.

Answer 7

Low order explosions

Question 8

It has less optimal efficiency of explosion due to many factors such as outdated explosives, moisture, improper placing or constructing.

Answer 8

Low order explosions

Question 9

is the forced high heated air flow that propagates after the explosion.

Answer 9

Blast wind

Question 10

Some of the roles of forensics in explosion are as follows:

Answer 10

✓ Identifying the manner of explosion i.e., if it is accidental or intentional.
✓ Identifying the cause, origin, and nature of the explosion.
✓ Identifying the explosive substance involved.
✓ Identifying victims.
✓ Recovering the explosive used or what is left of it.
✓ Knowing the extent of damage and its after-effect.

Question 11

Motives in Cases of Intentional Bombing

Answer 11

Attention
• Political Extremism
• Hate
• Vandalism
• Vengeance
• Civil Rights
• Self-satisfaction
• Racketeering
• Monetary Gain

Question 12

Since bombing produces massive effects, this is sometimes performed as a strategic move by those who are trying to gain a considerable amount of attention for their cause.

Answer 12

Attention

Question 13

Due to their desire to force their political beliefs to everyone, political extremists often resort to execution of intentional bombings so as to induce fear.

Answer 13

Political Extremism

Question 14

____ is a strong emotion that can a drive a person to take revenge on people, groups, or organizations that may have wronged them or caused them pain in any way. Thus, the
person does violent acts such as intentional bombings.

Answer 14

Hatred or Vengeance

Hatred

Question 15

In the early times, especially when racism was prevalent, a lot of civil rights advocates and organizations became victims of racist attacks by intentional bombing.

Answer 15

Civil Rights

Question 16

Intentional bombings may also be done by those who find pleasure or a sense of self- satisfaction after causing harm to a large number of people or damage to places and
establishments.

Answer 16

Self-satisfaction

Question 17

Bombing may be of aid to the execution of criminal acts that involve extortion, or a scheme organized to extract illegal profits.

Answer 17

Racketeering

Question 18

a) Microscopy
b) Vapor Trace Analyzer (VTA)
c) Thin Layer Chromatography (TLC)
d) High Performance Liquid Chromatography (HPLC)
e) Greiss Reagents Visualization
f) Infrared Spectrophotometry
g) Capillary Electrophoresis

Question 19

is a technique that makes use of microscopes in order to obtain an enlarged view of parts of the residue that cannot be seen by the naked eye.

Answer 19

Microscopy

Question 20

it is the use of a microscope as a means of

Answer 20

visual examination

Question 21

aids in sifting through evidence to find explosive residues from the scene.

Answer 21

Vapor Trace Analyzer (VTA)

Question 22

It analyzes vapors of substances with low vapor pressure like explosives.

Answer 22

Vapor Trace Analyzer (VTA)

Question 23

In this method, various explosives can be conveniently separated through the stationary and mobile phase analysis.

Answer 23

Thin Layer Chromatography (TLC)

Question 24

TLC is used to separate components of a mixture using the
____

Answer 24

stationary phase

Question 25

is a widely used analytical technique which can separate, identify, and measure the elements of a mixture.

Answer 25

High-Performance Liquid Chromatography (HPLC)

Question 26

It is used to detect nitrites embedded in, or deposited on, the skin of a victim, the surface of a target, or the hands of the shooter.

Answer 26

Griess Reagents Visualization

Question 27

This test can be extensively used because they will
color most nitrate-containing compounds bright red.

Answer 27

Griess Reagents Visualization

Question 28

It is used to determine functional groups in molecules and is widely used for structural and functional group analyses.

Answer 28

Infrared Spectrophotometry

Question 29

Because chromatographic methods provide only tentative
identification, this is used as a _____
