Cooling and heating system involves the collection and dissipation of heat appropriately. Heat gradient is important for heat transfer between systems because heat travels from the warmer system to the cooler system. The right medium for heat transfer is also important for this exchange – A good conductor of heat is required.
Answer:
The change in entropy of gas is 
Explanation:
n= Number of moles of gas
Change in entropy of gas = 

From the given,


Let "T" be the initial temperature.






Therefore, The change in entropy of gas is 
2,2,4-trimetilpentano is the answer.
I think that the correct answer is fission
