Calculate the internal energy (in Joules) of a system that loses 134.8 J that is compressed with a pressure of 5.73 atm from 8.5
Nataly_w [17]

The change in the internal energy of the system is -4511.8 J.

<h3>What is the change in the internal energy?</h3>

We know that according to the first law of thermodynamics, energy can neither be created nor destroyed  but can be transformed from one form to the other.

Now we know that;

ΔE = q + w

ΔE = Change in internal energy

q = heat absorbed or evolved

w = work done

Now we have;

q = - 134.8 J (The system losses heat)

w = PdV

w =  5.73 (1.00 -  8.540)

w = -43.2 Latm or -4377 J

Then we have;

ΔE = - 134.8 J + (-4377 J)

ΔE = -4511.8 J
