Question

Name the process by which nuclear energy is generated and also name one substance used for it. Give two advantages and two hazarda of nuclear energy

Answer 1

the nuclear energy is generated by two types 1. nuclear fission 2. nuclear fusion
uranium is used
advantage -1. it produces large amount of energy from small amount of nuclear fuel.
2. it does not produce gases like carbon dioxide which contribute to greenhouse effect.
disadvantage -1. the waste products of nuclear fission reactions are radioactive which keeps on emitting harmful radiation for thousands of years. 2. if there is leakage of radioactive materials which can cause serious damage to the plants,animals and the environment.

Answer 2

The two Process by which nuclear energy os generated -- 1) Nuclear fission 2) nuclear fussion

Uranium is used.

Advantages--

1) it release a large amount of energy.

2) it does not produce smoke, and eco-friendly

Hazardas--

1) Their is always a chance of lekage in the nuclear power plant which causes a very dangerous incident.

2) the waste materials produce by nuclear fission reaction is radioactive which keeps on emitting a harmful radiation for thousand of years.
