Q. An ideal gas expands in such a manner that its pressure and volume can be related by equation PV2 = constant. During this process, the gas is?
For an isothermal process, PV = constant and for the given process PVV = constant.
Therefore the gas is cooled because volume expands by a greater exponent than in an isothermal process.
Q. A gas has?
A gas can have any value of specific heat ranking from zero to infinity. For an isothermal change taking place in a gas, C is infinity, while for an adiabatic change, C is zero.
Q. If a monoatomic gas undergoes a thermodynamic process for which its molar heat capacity is equal to the universal gas constant. The process in terms of V and T is?
given C =R
dQ / ndT = R
(nCvdT + dW )/ ndT = R
Cv + pdV/ ndT = R
Cv = 3R /2
put in previous equation you will get
pdV / ndT = - R /2
using ideal gas p/n = RT / V
therefore RT / V*dV /dT = -R /2
dV / V = dT / 2T
integrate this equation , you will get
V T1/2 = contant
Q. The first law of thermodynamics incorporates the concepts of?
Conservation of energy and Equivalence of heat and work.
Q. How can i decide whether the cyclic process is clockwise or anticlockwise?
On a pressure volume diagram or temperature entropydiagram, the clockwise and counterclockwise directions ,If the cycle goes clockwise, the system does work ( i.e volume increase ) and vice -versa.
