Abhishek Chandra Solutions for Chapter: Sources of Energy, Exercise 2: EXERCISE

Which process is carried out at a higher temperature - nuclear fission or nuclear fusion?

The mass number of three elements: A, B and C are $2$, $180$ and $235$. Which one of them is suitable for making a hydrogen bomb?

What type of energy is possessed by huge waves near the sea shore?

(thermal energy/ potential energy/ kinetic energy)

The type of energy that we have not been able to control is 

Match the sources of energy in Column I to the locations where they are harnessed in Column II.

Two nuclear reactions are given below :

$\left(A\right) {}_{92}{}^{235}U + {}_0{}^{1}n \to {}_{56}{}^{139}Ba + {}_{36}{}^{94}Kr + wa + E$
(B) ${}_1{}^{2}H + X \to y + zb + E$

What are E, a, b, x and y? What are the numbers w and z?

Two nuclear reactions are given below:
$\left(A\right) {}_{92}{}^{235}U + {}_0{}^{1}n \to {}_{56}{}^{139}Ba + {}_{36}{}^{94}Kr + wa + E$
$\left(B\right) {}_1{}^{2}H + X \to y + zb + E$

Name the process represented by each of the two reactions.
