Heat and Thermodynamics 4 Question 34
36. From the following statements concerning ideal gas at any given temperature
(a) The coefficient of volume expansion at constant pressure is the same for all ideal gases
(b) The average translational kinetic energy per molecule of oxygen gas is
(c) The mean-free path of molecules increases with decrease in the pressure
(d) In a gaseous mixture, the average translational kinetic energy of the molecules of each component is different
Show Answer
Answer:
Correct Answer: 36. (a,c)
Solution:
- For one mole of an ideal gas
The coefficient of volume expansion at constant pressure is given by,
The average translational kinetic energy per molecule is (3/2)
