There are two samples A and B, which contains two different gases. Each sample has one mole of a gas. Graph between internal energy (E) and temperature (T) as shown in figure, then:

A

A contains He, B contains `N_2`

B

B contains `N_2`, A contains `O_2`

C

A contains `CO_2`, B contains He

D

A contains He, B contains `CO_2`

Text Solution

Verified by Experts

The correct Answer is:
C
`E = f/2 RT` for 1 mole when f is degree of freedom. Slop `= (fR)/2` is greater for A `rArr f_A gt f_B`

Two rigid boxes containing different ideal gases are placed on a table. Box A contains one mole of nitrogen at temperature T_0 , while Box contains one mole of helium at temperature (7/3)T_0 . The boxes are then put into thermal contact with each other, and heat flows between them until the gasses reach a common final temperature (ignore the heat capacity of boxes). Then, the final temperature of the gasses, T_f in terms of T_0 is

Consider the adjacent figure. A piston divides a cylindrical container into two equal parts. The lets part contains 1 mole of helium gas and the right part contains two moles or oxygen gas. The initial temperatures and pressures of the gases in the left chamber are T_(0) and p_(0) and the right chamber are (T_(0))/(2) and p_(0) respectively as shown in the figure. The piston as well as the walls of the container are adiabatic. After removal of the piston, gases mix homoganeously and the final pressure becomes p=(4n)/(13)p_(0) . Find the value of n.
