Thermodynamics question
This is the question:
A 0.2 m3 adiabatic rigid container is divided into two equal sections by a thin membrane
and one of these chambers is filled with air at 700 kPa and 36°C while the other chamber is
evacuated. Determine the internal energy change, the work done and the entropy change of the
gas when the membrane is ruptured.
This is all thats given and the answer is theres no change in internal energy as adiabatic, no work done as no change in volume of vessel but an entropy increase of 155 joules per kelvin.
Does anyone know how to get this answer as im struggling to find a way to get that number.
