Why is the average velocity of the molecules in a gas is zero but the average of square of velocity is not zero?

The average gas molecule velocity is zero, since there are just as many gas molecules going right (+ velocity) as there are going left (- velocity). This is why we square the velocities first, making them all positive. This ensures that taking the mean (i.e. average value) will not give us zero.

Why is average velocity of gas molecules in container zero?

If the center of mass of the gas being considered is at rest, then the average velocity of the constituent particles must be zero. If the container of gas is moving in some direction, then the average velocity of the gas molecules will be equal to the velocity of the center of mass of the container.

Why is the root mean square velocity of gas particles always larger than the average velocity?

For any list of numbers holds: The root mean square (rms) is always equal or higher than the average (avg). The reason is that higher values in the list have a higher weight (because you average the squares) in the calculation of a rms compared to the calculation of the avg.

What is the average velocity of the molecules of an ideal gas?

zero
Average velocity of an ideal gas molecule is zero.

What is the average velocity of the air molecules in the room where you are right now?

about 500 m/s
For typical air at room conditions, the average molecule is moving at about 500 m/s (close to 1000 miles per hour).

What is the average speed of gas molecules in a container?

The average velocity of gas molecules in a container moving in one direction is zero otherwise all molecules will be collected in one direction .

What is the average velocity of the molecules in the room you are sitting in at the moment is this a useful quantity?

For typical air at room conditions, the average molecule is moving at about 500 m/s (close to 1000 miles per hour). Note that the speed of sound is largely determined by how fast the molecules move between collisions, and not on how often they make collisions. This is because no energy is lost during the collisions.

What is the average velocity of the molecules of an ideal gas * 2 points Infinity constant zero unstable?

Average velocity of an ideal gas molecule is zero.

What is the relationship between the average velocity root-mean-square velocity?

α:V:U=√2:√8π:√3=1:1.128:1.224.

What is the difference between average molecular speed and root-mean-square velocity?

– The average speed is the sum of the speeds of all the molecules divided by the number of molecules. – The root-mean-square speed is the measure of the speed of particles in a gas, defined as the square root of the average velocity-squared of the molecules in a gas.
