Describe the particle theory properties of a gas. a. How close are the molecules? b. How do the molecules move and interact with each other? c. How densely packed are the particles? d. How strongly are they attracted to each other?
The beautiful results which the founders of the kinetic theory of gases were able to attain by regarding gas molecules simply as rigid elastic spheres have been considerably refined in several directions by theorists who have imagined a gas molecule which exerts a weak attractive force on its ...
There are two ways atoms can bond with each other. (a) Describe both of them. (b) Which of these two types of bonds do atoms use to make a molecule? Two water molecules are weakly attracted to each other when a slightly positive hydrogen atom in ...
One of the assumptions of kinetic theory of gases states that "there is no force of attraction between the molecules of a gas". How far is this statement correct ? Is it possible to liquefy an ideal gas ? Explain. View Solution

high-energy X-rays and ultraviolet (UV) radiation from the Sun. However, because the gas molecules are so dispersed, there isn’t enough density for this heat to be felt in the same way it would be at lower altitudes—essentially, the air is too thin to effectively transfer this energy....
$\begingroup$ Gravity on individual gas molecules is mostly irrelevant. Individual molecules bounce off each other like billiard balls in every direction thousands of times per second. The rate they "fall" isn't a significant factor. Warmer air wants to rise because it's lighter, co...
Five gas molecules chosen at random are found to have speeds of 500,600m,700,800 and 900 m/s Then, Athe rms speed and the average speed are the same Bthe rms speed is 14m/s higher than the average speed Cthe rms speed is 14m/s higher than the average speed Dthe rms speed is...
