Q. 3 B4.2( 17 Votes )
The coolant in a chemical or a nuclear plant (i.e., the liquid used to prevent the different parts of a plant from getting too hot) should have high specific heat.
The coolant in a chemical or nuclear plant should have a high specific heat since amount of heat transferred to a body is proportional to its Specific heat, so if specific heat is higher it could absorb more heat itself thus preventing other parts of plant from getting too hot and itself consuming most of the excess heat produced in the chemical or nuclear Plant.

In changing the state of a gas adiabatically from an equilibrium state A to another equilibrium state B, an amount of work equal to 22.3 J is done on the system. If the gas is taken from state A to B via a process in which the net heat absorbed by the system is 9.35 cal, how much is the net work done by the system in the latter case? (Take 1 cal = 4.19 J)NCERT - Physics Part-II
