PHXI12:THERMODYNAMICS

371474 During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The \(\gamma\) of the gas is

1 1.5
2 1.3
3 2
4 1.7
PHXI12:THERMODYNAMICS

371475 Compressed air in the tube of a wheel of a cycle at normal temperature suddenly starts coming out from a puncture. The air inside

1 Starts becoming hotter
2 Remains at the same temperature
3 Starts becoming cooler
4 May become hotter or cooler depending upon the amount of water vapour present

371476 In an adiabatic compression the volume of an ideal gas decreases to \({\frac{1}{8}^{th}}\) of its initial value. Its final pressure becomes \(\left(\gamma=\dfrac{5}{3}\right)\)

1 8 times the initial pressure
2 16 times the initial pressure
3 32 times the initial pressure
4 None of the above
PHXI12:THERMODYNAMICS

371477 A sound wave passing through air at NTP produces a pressure of \(0.001\,dyne/c{m^2}\) during a compression. The corresponding change in temperature (given \(\gamma=1.5\) and assume gas to be ideal) is

1 \(8.97 \times {10^{ - 8}}\;K\)
2 \(8.97 \times {10^{ - 4}}\;K\)
3 \(8.97 \times {10^{ - 6}}\;K\)
4 None of these
