Question 382: Thermodynamics & KTG

Question

An ideal gas in a cylinder is separated by a piston in such a way that the entropy of one part is S1 and that of the other part is S2. Given that S1 > S2. If the piston is removed then the total entropy of the system will be :

Accepted Answer

for gas 1, S
1
= $${f \over 2}{n_1}R$$
for gas 2, S
2
= $${f \over 2}{n_2}R$$
after removal of piston,
S = $${f \over 2}({n_1} + {n_2})R = {S_1} + {S_2}$$

Answer

S1 $$-$$ S2

Answer

$${{{S_1}} \over {{S_2}}}$$

Answer

S1 $$	imes$$ S2

Answer

S1 + S2
