It is denoted by C P. Its S.I. unit is J K-1 mol-1. Relation Between C P and C V: C P – C V = R
Web1.365. In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure ( CP) to heat capacity at constant volume ( CV ). It is sometimes also known as the isentropic expansion factor and is denoted by ... WebThe relationship between C P and C V for an Ideal Gas. From the equation q = n C ∆T, we can say: At constant pressure P, we have. qP = n CP∆T. This value is equal to the change in enthalpy, that is, qP = n CP∆T = ∆H. Similarly, at constant volume V, we have. qV = n CV∆T. This value is equal to the change in internal energy, that is,
WebA flexible balloon contains 0.340 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7200 cm3 and a temperature of 22.0 ∘C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as ...
WebSep 12, 2024 · When an ideal gas is compressed adiabatically \((Q = 0)\), work is done on it and its temperature increases; in an adiabatic expansion, the gas does work and its temperature drops.
