The root mean square velocity of a gas particle is equal to the square root of (3RT/M), where R is the gas constant (in J K^-1 mol^-1), T is temperature in Kelvin (around 293 at room temperature) and M is molar mass (0.028 kg/mol for diatomic nitrogen, which makes up >50% of the atmosphere. Plugging in these values gives approximately 511 m/s.
Molecules in the air move at speeds that vary due to factors like temperature and pressure. On average, at room temperature, most molecules in the air move at speeds ranging from 300-500 meters per second.
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.
Air molecules at room temperature (~20°C) typically move at speeds around 500 m/s. This movement contributes to air pressure and properties such as diffusion and convection.
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.
In a room, the different molecules making up the air have, on average, the same kinetic energy. This is governed by the ideal gas law and the distribution of kinetic energies within a gas at a particular temperature. Despite differences in mass and speed, the average kinetic energy remains constant for a given temperature.
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.
The average speed of oxygen molecules in air at room temperature (around 20°C) is approximately 460 meters per second. This speed can vary depending on factors such as temperature and pressure.
Temperature is always measured when surface have transition from hot to cold or vice-versa. When molecules decrease in density, implies the individual molecules get cooler/hotter faster to room temp.hence,When air molecules decrease air temperature rapidly changes to room temperature or ambient temperature.

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 molecules of air in a room have different speeds due to collisions with each other and with surfaces in the room. This leads to a range of speeds, known as a Maxwell-Boltzmann distribution. Additionally, the temperature of the room causes the molecules to have different kinetic energies, influencing their speeds.
The speed of sound in air is directly proportional to the square root of the temperature. This is because sound travels through air by compressing and expanding air molecules, and the speed of this propagation is faster in warmer air because the molecules move faster and can transmit the sound energy more quickly.

The speed of gas molecules is primarily determined by their temperature, not their specific identity. At the same temperature, bromine molecules and air molecules would have similar average speeds.
Air molecules at room temperature (~20°C) typically move at speeds around 500 m/s. This movement contributes to air pressure and properties such as diffusion and convection.
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.
Isaac Newton calculated the speed of sound in air at room temperature to be around 343 meters per second.
