Q1. If one mole of a monoatomic gas (Î³ = 5/3) is mixed with one mole of diatomic gas (Î³ = 7/5), the value of Î³ for the mixture is

•  1.40
•  1.50
•  1.53
•  3.07

Q2. A gaseous mixture contains equal number of hydrogen and nitrogen molecules. Specific heat measurements on this mixture at temperatures below 150 K would indicate that the value of Î³ (ratio of specific heats) for this mixture is

•  3/2
•  4/3
•  5/3
•  7/5

Q3. A mixture of n1 moles of monoatomic gas and n2 moles of diatomic gas has Î³ = 1.5, then

•  n1 = 2n2
•  2n1 = n2
•  n1 = n2
•  2n1 = 3n2

Q4. Two ideal gases at temperature T1 and T2 are mixed. There is no loss of energy. If the masses of molecules of the two gases are m1 and m2 and number of their molecules are n1 and n2 respectively, the temperature of mixture will be

•  (T1 + T2) / (n1 + n2)
•  T1/n1 + T2/n2
•  n2T1 + n1T2 / n1 + n2
•  n1T1 + n2T2 / n1 + n2

Q5. Two moles of a monoatomic gas are mixed with one mole of a diatomic gas. The Î³ for mixture is

•  5/3
•  7/5
•  4/3
•  17/11
