Experiment 1.When the two containers are weighed, `W_A = 225 g, W = 160 g` and mass of evacuated container `W_C = 100 g`.
Experiment 2.When the two containers are given same amount of heat, same temperature rise is recorded. The pressure change found are
`Delta P_A = 2.5 atm, Delta P_B = 1.5 atm`

A

`N_2 , Ne`

B

`He, H_2`

C

`O_2 , Ar`

D

`Ar, O_2`

Text Solution

Verified by Experts

The correct Answer is:
D
Since `n_1 = 5/3 n_2` Therefore `125/M_A = 5/3 (60/M_B)`
(From experiment `1 : W_A = 25` gm and `_W_B = 60 gm `)
`rArr " "5M_B = 4 M_A`
The above relation holds for the pair–Gas A : Ar and Gas `B: O_2`

Two adiabatic containers have volumes V_(1) and V_(2) respectively. The first container has monoatomic gas at pressure p_(1) and temperature T_(1) . The second container has another monoatomic gas at pressure p_(2) and temperature T_(2) . When the two containers are connected by a narrow tube, the final temperature and pressure of the gases in the containers are P and T respectively. Then
