Answer:
0.79014 J
Explanation:
According to the first law of thermodynamics:-
Where,
U is the internal energy
q is the heat
w is the work done
From the question,
q = 0 J
The expression for the calculation of work done is shown below as:
Where, P is the pressure
is the change in volume
From the question,
= 3 - 1 L = 2 L
P = 400 Pa
The expression for the conversion of pressure in Pascal to pressure in atm is shown below:
P (Pa) = P (atm)
Given the value of pressure = 43,836 Pa
So,
400 Pa = atm
Pressure = 0.0039 atm
Also, 1 atmL = 101.3 J
So,
(work is done by the system)
So,
