Question 324: 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 S
1
and that of the other part is S
2
. Given that S
1
> S
2
. 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

S
1

Answer

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

Answer
