Q: Which of the following statements is not true regarding the effect of increasing temperature on the distribution of molecular motion in a gas-
  • A. Most likely speed increases
  • B. The fraction of molecules increases with the maximum possible speed
  • C. Delivery becomes widespread
  • D. The area under the distribution curve remains the same as below the lower temperature value.
Correct Answer: Option B - The effect of an increase in temperature on the distribution of molecular motion in gases increases the maximum possible speed. The distribution becomes wider and the area under the distribution curve remains the same as under the lower temperature but the potential speed of the molecules in that region As the fraction of the molecule does not increase hence statement (b) is not true. The kinetic energy of the molecules of gases is proportional to the ultimate temperature of the gaseous system, the gas molecules do not attract each other. They move independently.
B. The effect of an increase in temperature on the distribution of molecular motion in gases increases the maximum possible speed. The distribution becomes wider and the area under the distribution curve remains the same as under the lower temperature but the potential speed of the molecules in that region As the fraction of the molecule does not increase hence statement (b) is not true. The kinetic energy of the molecules of gases is proportional to the ultimate temperature of the gaseous system, the gas molecules do not attract each other. They move independently.
