When a sample of a gas is compressed at ...

When a sample of a gas is compressed at constant temperature from 15 atm to 60 atm, its volume changes from `76 cm^3` to `20.5 cm^3`. Which of the following are possible.

A

The gas shows non-ideal behaviour

B

The gas dimerizes

C

The gas is adsorbed onto the vessel walls

D

The gas molecules have repulsions to each other

Text Solution

Verified by Experts

`P_1V_1 = 15 xx 76 = 1140`
`P_2V_2 = 60 xx 20.5 = 1230` = non ideal behavious
If it was ideal, `V_2 = 19`
`= V_r > V_i = Z > 1 = ` repulsions dominate.

A gas is compressed at a constant pressure of 50 N//m^(2) , from a volume 10 m^(3) to a volume of 4 m^(3) . 100 J of heat is added to the gas then its internal energy.

A gas absorbs 100 J of heat and is simultaneously compressed by a constant external pressure of 1.5 atm from a volume of 8.0L to 2.0L. The change in internal energy for the gas in Joules is (1L - atm = 101.32 J))

When 5 moles of an ideal gas is compressed isothermally, its volume decreases from 5 litre to 1 litre. If the gas is at 27^(@) C, find the work done on the gas.

When 3.0 mole of an ideal diatomic gas is heated and compressed simultaneously from 300K, 1.0 atm to 400K and 5.0atm, the change in entropy is (Use C_(P) = (7)/(2)R for the gas)

One mole of an ideal monoatomic gas expands isothermally against constant external pressure of 1 atm from initial volume of 1l to a state where its final pressure becomes equal to external pressure. If initial temperature of gas is 300K then total entropy change of system in the above process is: [R =0.082L atm mol^(-1)K^(-1)= 8.3J mol^(-1) K^(-1) ]
