Question 81 of 190

The workdone in an adiabatic change in an ideal gas depends upon only :

Show answer and solution

Answer: (A) change in its temperature

Work done in adiabatic process

=\frac{n R \Delta T}{1-\gamma}

So, depends upon change in temperature.

ThermodynamicsThere are two vessels filled with an ideal gas where volume of one is double the volume of other. The large vessel contains the gas at 8 kPa at 1000 K while the smaller vessel contains the gas at 7 kPa at 500 K. If the vessels are connected to each other by a thin tube allowing the gas to flow and the temperature of both vessels is maintained at 600 K , at steady state the pressure in the vessels will be (in kPa).
ThermodynamicsAn ideal gas goes from an initial state to final state. During the process, the pressure of gas increases linearly with temperature.
A. The work done by gas during the process is zero.
B. The heat added to gas is different from change in its internal energy.
C. The volume of the gas is increased.
D. The internal energy of the gas is increased.
E. The process is isochoric (constant volume process)
