An atom bomb works on :

  1. Electrical energy

  2. Heat energy

  3. Mechanical energy

  4. Atomic energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Atomic energy 

Atomic energy is the energy that is created by splitting apart the nuclei of atoms.  The atomic energy is released during the process of fission.  The basic principle of atom bomb is uncontrolled nuclear fission.

The essential distinction between X-rays and $\gamma$-rays is that the $\gamma$-rays :

  1. have greater ionizing power than X-rays

  2. emanate from nucleus, white X-rays emanate from outer part of the atom

  3. have smaller wave-length than X-rays

  4. none of the above 
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A 

Gamma-rays have the highest energy in the EMR spectrum and their waves have the shortest Wavelength. Gamma rays are lot more dangerous and hazardous to human health than X-rays. Moreover gamma rays are the highly penertating and highly energetic ionizing radiation.

Principle of Hydrogen bomb is .................. reactions.

  1. Uncontrolled fusion

  2. Fission

  3. Controlled fusion

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A hydrogen bomb operates on the principle of uncontrolled nuclear fusion. Unlike fission bombs, which split heavy atoms, fusion bombs release energy by combining light nuclei in a rapid, explosive chain reaction.

Which bomb works on the principle of Nuclear fusion ?

  1. Atom bomb

  2. Hydrogen bomb

  3. Neutron bomb

  4. Nuclear reactor
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Nuclear fusion is a nuclear reaction in which two or more atomic nuclei at a very high speed and join to form a new type of atomic nucleus. Fusion reactions are high energy reactions in which two lighter atomic  nuclei fuse to form a heavier nucleus. This fusion reaction is taking place in hydrogen bomb.

Kerosene burns more rapidly than coke because

  1. It has got more oxygen in it than coke

  2. It is a liquid hydrocarbon

  3. It has a low ignition temperature

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ignition temperature is the minimum temperature at which a substance catches fire. Kerosene has a lower ignition temperature than coke, allowing it to ignite and burn more rapidly.

Destructive distillation of coal leads to the formation of

  1. Wood

  2. Kerosene

  3. Amino acid liquor

  4. Charcoal
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The destructive distillation of coal produces coal gas, coal tar, and ammoniacal liquor (often referred to as amino acid liquor in some contexts). Wood and kerosene are not products of coal distillation.

Which of the following is not an example of spontaneous combustion?

  1. Burning of liquified petroleum gas

  2. Fire caused in coal mines

  3. Dry white phosphorous liberates white fumes on exposure to air

  4. All of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Spontaneous combustion occurs without an external ignition source. LPG requires an external spark or flame to ignite, so it is not an example of spontaneous combustion.
