Assume a cylinder is divided into two parts. One part is filled with air, the other is evacuated. If a small hole is opened between the two halves so that the air fills both parts, what will happen to the entropy?

a

The entropy will increase.

b

The entropy will stay the same.

c

The entropy will decrease.

Answer #1

ask in comment box if any doubts and please do thumbs up.

entropy of system is degree of randomness of system.

here air through the small hole will increase the randomness of the system .

for every process the total entropy of the system will increase

so answer is option a

    As shown in the figure, a sealed cylinder of ideal gas is divided into two parts by a piston that can move up and down without friction. There is ideal gas in both parts, but the gas from one part is isolated from that in the other part by the piston. The volume occupied by the gas in the lower part is twice that occupied by the gas in the upper part, while the temperature is the same in both...

    An isolated chamber with rigid walls is divided into two equal compartments, one containing steam at 10 bar and 370oC, and the other evacuated. A valve between the compartments is opened to permit steam to pass from one chamber to the other. a)After the pressure (but not the temperatures) in the two chambers have equalized, the valve is closed, isolating the two systems. What are the temperature and pressure in each cylinder?b)If the valve were left open, and equilibrium state...
