Which of the following statements is TRUE?
Which of the following statements is TRUE?
A) The higher the temperature, the lower the average kinetic energy of the sample
B) At low temperatures, intermolecular forces become important and the pressure of a gas will be lower than predicted by the ideal gas law.
C) The smaller a gas particle, the slower it will effuse
D) At a given temperature, lighter gas particles travel more slowly than heavier gas particles.
Homework Answers
The true statement is B)
This comes from the fact that at low temperatures, the gases will move slower meaning that the effect of intermolecular attraction becomes predominant. On taking into account these attractions, the pressure of the gas will be lower
Decide which of the following statements are true and which are false.
Decide which of the following statements are true and which are false. As temperature increases, the average kinetic energy of a sample of gas molecules decreases. Ideal gas molecules have small volumes and exert weak attractive forces on one another. At constant temperature, the lighter the gas molecules, the smaller the average velocity. In order for two separate 1.0 L samples of O2(g) and H2(g) to have the same average velocity, the O2(g) sample must be at a higher temperature than the H2(g) sample. Real...

Part A) Which of the following statements is true for ideal gases, but is not always true for real gases? Choose all that apply. Molecules are in constant random motion. Pressure is caused by molecule-wall collisions. The size of the molecules is unimportant compared to the distances between them.

T20 is the “heavier' isotopologue of H20. Without explicit calculation of the translational partition function (qtrans), predict which molecule has a higher value of qtrans at a given temperature and pressure. You may assume the ideal gas approximation. Select one: O a. T20 would have a smaller (trans because it has more kinetic energy. b. H2O would have a larger qtrans because it is lighter. c. H2O would have a smaller Otrans because it is lighter....

The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles (n): PV=nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van...
