Question
(a) We showed in class that for adiabatic processes that the pressure P and volume V satisfy P = constant. where is the so-called adiabatic exponent which is related to the number of degrees of freedom f per molecule via -(f + 2)/f. Now suppose that our ideal gas is actually composed of two different gases 1 and 2, each with its own number of degrees of freedom per molecule f1,2, respectively, which would correspond to two different exponents 1,2 The total energy U of the gas, then, may be written as 2T2 where n1,2 are the fractions of the N gas particles that are either type 1 or 2 (so that ni +n2-1). Starting from this, repeat the derivation shown in class and in the textbook on pages 25-26 and show that P = constant. (10) where satisfies the relation Tn m2 (Hint: Once you find how is related to n1,2 and 1,2, it may be helpful to work backwards from the relation you have to show.) (3 points)Explanation / Answer
A. collision will be inelastic type because energy is not conserved in this case i.e its some of energy is lost.
B. Yes it is true that heat ransfer is irreversible and momometum conservation is reversible because in during heat energy is lost but in elastic collision no energy is lost.
