Schrodinger developed a famous equation that allows the solutions for electron wave functions to be found given a specific potential. For the case of an atom, Schroginger's equation allows the determination of electron wave functions. These wave functions tell us how electrons are distributed in space around the atom.

Answer:
15.24 J is the change in internal energy for this process.
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 = + 75 J
(+ sign as the heat is being absorbed)
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,
= 2.00 - 1.40 L = 0.60 L
P = 1.02 atm
Also, 1 atmL = 101.3 J
So,
(work is done by the system)
So,

<u>15.24 J is the change in internal energy for this process.</u>
