Which Gas Has Lowest Average Velocity? The gas with the highest molar mass is H2Se, which means it will have the lowest average speed. What gas has the highest average velocity? At a particular temperature, the average kinetic energy of all gaseous molecules is equal. Since hydrogen gas has the lowest mass out of these
What Kind Of Air Is In Space? In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. ‘Outer space’ begins about 100 km above the Earth, where the shell of air around our planet disappears. Are
Which Of The Following Are Postulates Of Kinetic Molecular Theory? The kinetic-molecular theory of gases can be stated as four postulates: A gas consists of molecules in constant random motion. Gas molecules influence each other only by collision; they exert no other forces on each other. All collisions between gas molecules are perfectly elastic; all
Why Does Gas Pressure Increase When More Particles Are Added? Adding more molecules of a gas increases the number of collisions between the molecules and the walls of the container. This raises pressure. … By their very nature, gases can be compressed, so if the same gas can be put into a smaller container, it
Why Does The Pressure Inside A Container Of Gas Increase If More Gas Is Added To The Container Brainly? When the temperature of a sample of gas in a rigid container is increased, the pressure of the gas increases as well. The increase in kinetic energy results in the molecules of gas striking the walls
Why Does The Pressure Exerted By Gas Not Depend On The Type Of Gas? If the temperature is constant, as the pressure of a gas increases, the volume decreases. … The pressure exerted by a gas does not depend on the type of gas because the factors that differentiate gasses don’t affect the pressure exerted
What Is The Relationship Between Temperature And Volume As Explained By The Kinetic Molecular Theory? Charles’ law: for a fixed mass of gas at constant pressure the volume is directly proportional to the temperature. Analysis of a gas when its temperature increases according to kinetic theory: The temperature has increased therefore the molecules have more
Why Do Real Gases Have Attractive Forces? Repulsive forces: As a gas is compressed, the individual molecules begin to get in each other’s way, giving rise to a very strong repulsive force acts to oppose any further volume decrease. … The more electrons in the molecule (and thus the greater the molecular weight), the greater
Why Do Gas Molecules Move Away From Each Other? Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. Do molecules in gas move away from each other?
How Do You Find A And B/in Van Der Waals Equation? The van der Waals equation is frequently presented as: (P+an2V2)(V−nb)=nRT ( P + a n 2 V 2 ) ( V − n b ) = n R T . The constants a and b represent the magnitude of intermolecular attraction and excluded volume
