Answer to Question #288298 in Molecular Physics | Thermodynamics for harry

Question

In an adiabatic process, 550 J of net work is done on a gas to significantly reduce its volume. Determine the change in internal energy of the gas?

Answer 1

Adiabatic process

$dQ=0$

We know that

$dQ=dU+dW$

$dU=dQ-dW$

$dU=-dW$

Where $dW=550J$

Internal energy

$dU=-550J$
