State one use of nuclear fission reactions.

Critical state of disease is called:

Consider the following statements : 1. The chain reaction process is used in nuclear bombs to release a vast amount of energy, but in nuclear reactors, there is no chain reaction. 2. In a nuclear reactor, the reaction is controlled, while in nuclear bombs, the reaction is uncontrolled. 3. In a nuclear reactor, all operating reactors are 'critical', while there is no question of 'criticality' in case of a nuclear bomb. 4. Nuclear reactors do not use moderators, while nuclear bombs use them. Which of the above statements about operational principles of a nuclear reactor and a nuclear bomb is/are correct?

Demonstrate that Eqs. (2. 6a) and (2 . 6b) are valid for a substance, obeying the Van der Qaals equation, in critical state Make use of the fact that the critical state corresponds to the point of inflection in the isothermal curve p (V) .
