The average speed of hydrogen molecules at room temperature (around 25°C) is approximately 1.9 km/s. This speed is calculated based on the Maxwell-Boltzmann distribution of molecular speeds.

What does the experiment suggest about the average speed of hydrogen molecules compared with the average speed of molecules in the air?

The experiment suggests that the average speed of hydrogen molecules is higher than the average speed of molecules in the air. This is because hydrogen molecules are lighter and have a higher root mean square speed due to their lower mass.


Why do oxygen molecules move slowly than hydrogen molecules at the same temperature?

Oxygen molecules are heavier than hydrogen molecules, so they have a slower average speed at the same temperature. This is because the speed of gas molecules is directly related to their mass - lighter molecules like hydrogen move faster than heavier molecules like oxygen.


What measures the average speed of air molecules?

The temperature of a gas is related to the average kinetic energy of its molecules, which is directly proportional to their speed. Therefore, temperature indirectly measures the average speed of air molecules.


The average speed of the molecules of a gas is proportional to the?

The average speed of gas molecules is proportional to the square root of the temperature of the gas. As the temperature increases, the average speed of the molecules also increases. This is described by the Maxwell-Boltzmann distribution of speeds.


How does the average speed of air molecules relate to the temperature?

The average speed of air molecules increases with temperature. This is because higher temperatures provide more thermal energy to the molecules, causing them to move faster on average. Conversely, lower temperatures result in slower average speeds of air molecules.


What is the ratio of the average velocity of hydrogen molecules to that of neon atoms at the same temperature and pressure?

The ratio of the average velocity of hydrogen molecules to neon atoms is the square root of the ratio of their molar masses. Since the molar mass of neon is about 20 times that of hydrogen, the average velocity of hydrogen molecules would be about √20 times faster than that of neon atoms.


How does the average speed of the water molecules change as they are heated?

As water molecules are heated, their average speed increases. This increase in speed is due to the increase in kinetic energy of the molecules, causing them to move faster. This relationship is described by the kinetic theory of gases.


A measure of the speed of molecules is the?

A measure of the speed of molecules is the temperature of the substance they are in. Temperature is related to the average kinetic energy of the molecules, and the higher the temperature, the faster the molecules will be moving.


Average speed of air molecules?

The average speed of air molecules at room temperature is around 500 m/s. However, the speed can vary depending on factors such as temperature and pressure.


How does the speed of molecules of gas change when heated?

When gas molecules are heated, their kinetic energy increases, causing them to move faster. This increase in speed leads to higher average velocity and greater collisions with other molecules, resulting in an overall increase in the gas pressure and volume.


If you are heating an Oxygen Hydrogen gas do both of the elements molecules speed up at the same rate?

No, the molecules of hydrogen gas would speed up more than the molecules of oxygen gas when heating a mixture of the two gases because hydrogen gas has a lower molecular mass and thus higher average speed at a given temperature.


In which state will atoms and molecules have the lowest average speed?

Solids.
