As isolated box, equally partitioned contains two ideal gases A and B as shown

What the partition is removed, the gases mix. The changes in enthalpy `( Delta H)` and entropy `( Delta S)` in the process, respectively, are

A

zero, positive

B

zero, negative

C

positive, zero

D

negative, zero

Text Solution

Verified by Experts

The correct Answer is:
A
According to KTG
Force of attraction and repulsion amongst molecules of ideal gas are negligible
So, ` Delta H=0`
and randomness increases due to increase in volume so `Delta S = + ve`.

Two vessels divided by a partition cotain one mole of N_(2) and two moles of O_(2) gas. If the partition is removed and gases mixed isothermally, find the change in entrope due to mixing assuming initial and final pressure are same.

Two liquid A & B having densities 2rho and rho respectively, are kept in a cylindrical container separated by a partition as shown in figure. The height of each liquid in the container is h and area of cross section of the container is A. Now the partition is removed. Calculate change in gravitational potential energy ( DeltaU ) of the system (a) assuming that the two liquids mix uniformly. (b) Assuming that the two liquids are immiscible. What do you conclude from the sign of DeltaU in the above two cases?

An insulated cylindrical vessel is divided into three identical parts by two partitions 1 and 2. The left part contains O_(2) gas, the middle part has N_(2) and the third chamber has vacuum. The average molecular speed in oxygen chamber is V_(0) and that in nitrogen chamber is sqrt((8)/(7)) V_(0) . Pressure of the gases in two chambers is same. Partition 1 is removed and the gases are allowed to mix. Now the stopper holding the partition 2 is removed and it slides to the right wall of the container, so that the mixture of gases occupy the entire volume of the container. Find the average speed of O_(2) molecules now.
