In an adiabatic process, no transfer of ...

In an adiabatic process, no transfer of heat takes place between system and surroundings. Choose the correct option for free expansion of an ideal gas under adiabatic condition from the following.

A

`q = 0, Delta T ne 0, w = 0`

B

`q ne 0, Delta T = 0, w = 0`

C

`q = 0, Delta T = 0, w = 0`

D

`q = 0, Delta T lt 0, w ne 0`

Text Solution

Verified by Experts

The correct Answer is:
C
Work done in free expansion of an ideal gas is zero.
:. W = 0
Also,in an adiabatic process, q = 0
:. `Delta U = q + w = 0`
This means that during the process. `Delta U` remains constant. Therefore, during expansion no change in temperature takes plae.
:. `Delta T = 0`

The ratio of specific heats of a gas in 1.40 . There are 200 moles of gas initially present. The gas undergoes adiabatic expansion and as a result which, the temperature of the gas falls from 400 K to 100 K. Give R=8.312J "mole"^(-1) K^(-1) . Calculate the amount or work done by the gas on the surroundings.

In changing the state of a gas adiabatically from an equilibrium state A to another equilibrium state B, an amount of work equal to 22.3 J is done on the system. If the gas is taken from state A to B via a process in which the net heat absorbed by the system is 9.35 cal, how much is the net work done by the system in the latter case ? (Take 1 cal = 4.19 J)
