even no = 3/6 = 1/2
no. less than 5 = 4/6 = 2/3
Answer:
e. adiabatic process
Explanation:
Adiabatic process -
In the thermodynamic system , an adiabatic process is the one which involves no transfer of mass or heat of the substance , is referred to adiabatic process.
In this process , the temperature need not be constant ,
But only the heat is transferred into or out of the system .
Hence, from the given information of the question,.
The correct option is e. adiabatic process .
