ICS Part 2 Physics Chapter 21 Short Questions Preparation

Question # 1

What are thermal reactors?

Ans 1: The thermal reactors are called thermal reactors because the neutrons must be slowed down to thermal energies to produce further fission,They use natural uranium or slightly enriched uranium as fuel.

Question # 2

Discuss the advantages of fission power from point of view of safety,pollution and resources.

Ans 1: Advantage of nuclear power are given below
1. Nuclear fission energy,release a highly reduced amount of the gases into the air,resulting in a slower rate of global warming and pollution.
2. The energy is quick to create;meaning that they are able to make a large amount of some form of emergency required it.
3. Much more energy is produced.

Question # 3

Which radiation does would deposit more energy to the body(a)10 m Gy to the hand (b)1m Gy dose to entire body.

Ans 1: Since
absorbed dose=D=energy/mass
energy=D * Mass
since the mass of whole body is much greater than mass of the hand,therefore 1 Gy dose given to the entire body deposit more energy.

Question # 4

Write name of different quarks.

Ans 1: The name of different quarks are as follows
Up,Down-Strange ,Charm,Top,Bottom

Question # 5

What is self-quenching in Geiger Muller Counter?

Ans 1: A small amount of gas is added into the GM counter is called self quenching or internal quenching,In GM counter the phenomena of quenching is to save the counter from spurious or false counts.

Question # 6

Define Hadrons and Leptons.

Ans 1: Hadrons: These are not elementary particle,They are composed of other elementary particle called quarks.The example of hadrons are protons,neutrons,mesons etc,They experience strong nuclear force.
Laptons: The are elementary particles.They do not experience strong nuclear force,The example of laptons are electrons .muons and neutrinos etc.

Question # 7

Differentiate between parent and daughter element.

Ans 1: The change of an element into a new element due to emission of radiation is called radioactive decay.The original atom is called parent element and the element formed due to this decay is called daughter element.

Question # 8

What are isotopes?What do you have in common?

Ans 1: Isotopes are such nuclei of an element that have the same charge number Z but have different mass number A.
It means ,in the nucleus the number of protons is the same but the number of neutrons is different.

Question # 9

Differentiate between Baryons and Mesons.

Ans 1: Baryons:The particle equal in mass greater than protons are called baryons.It is made by 3 quarks.
Ans 2: Mesons: The particle which are lighter in mass than protons are called mesons,A pair of quark and an antiquark makes as meson.

Question # 10

Discuss the advantage and disadvantage of nuclear power compare to the use of fossil fuel generated power.

Ans 1: Advantage and disadvantage of nuclear power are given below compared to the use of fossil generated power.
Advantage:
1. Much more energy is produced.
2. Produces no environmental pollution.
3. Electricity produced in this way is far cheaper than fossil fuel generated power.
Disadvantage :
1. Uranium mining is more dangerous than coal mining.
2. Nuclear waster is very injurous and harmful to living things.
3. Nuclear waste can not be transported through area of population whereas fossil fuel can be.
