Answer:
U = 9253.6 J
Explanation:
It is given that,
Heat transferred in isochoric process,
Pressure in this process,
In the second step,
It is subjected to isobaric compression until its volume decreases by, (it decreases)
Heat transferred out of the gas,
In isochoric process, work done by the gas is zero as in this type volume is constant,
According to first law of thermodynamics,
.............(1)
In isochoric compression,
Let U is the total change in the internal energy of this gas. So,
U = 9253.6 J
So, the total change in the internal energy of this gas is $$9253.6 J. Hence, this is the required solution.
