Generally speaking, atoms slow down when cold and speed up when warm.
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.
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.
In solids, heat is the energy of vibrating molecules or atoms; the higher the temperature, the greater the vibration. And when molecules or atoms vibrate more, there will be more space between them.
In a gas, if volume decreases, the molecules have less space to move and collide with each other more frequently, increasing speed. In a liquid or solid, volume changes typically have less direct impact on speed compared to gases.
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.
it speeds it, as the extra speed of the air molecules tends to knock more water molecules off the surface of the body of water
Slow down and the temperature drops.
The higher the temperature, the more movement in the molecules, causing the substance to liquify, or turn to gas, whichever, more quickly than if there were no vibrations in the molecules.

The Hotter the temperature, the faster the particle moves. During the reaction, atoms transfer in different molecules (or compounds), therefore the temperature does affect the speed of the reaction.
The degrees of freedom of molecules determine how they can move and interact during a chemical reaction. Molecules with more degrees of freedom have more ways to move and rotate, which can affect the speed and outcome of the reaction. This can impact factors such as reaction rate, energy transfer, and overall reaction dynamics.
Temperature affects the speed of sound through material by kinetic energy. The more molecules the higher temperatures will have more energy.
An indirect measurement of the speed of molecules can be made using techniques such as Doppler spectroscopy or light scattering. These methods analyze the behavior of light as it interacts with the molecules to determine their speed indirectly. By studying the changes in the properties of the light, scientists can infer the motion and speed of the molecules.
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.
Temperature directly affects the speed of molecular movement in matter. As temperature increases, the molecules gain more energy and move faster. Conversely, as temperature decreases, the molecules slow down. This relationship is described by the kinetic theory of matter.
In solids, heat is the energy of vibrating molecules or atoms; the higher the temperature, the greater the vibration. And when molecules or atoms vibrate more, there will be more space between them.
The wheel size does affect its speed.
