How are the speeds of molecules of air affected when the air is compressedby the action of a tire pump?
When air is compressed by a tire pump, the speeds of air molecules increase. This is because the compression increases the pressure, causing the molecules to collide more frequently and with higher energy, leading to an increase in their average speed.
Why can gas move very fast and be compressed?
Gas molecules are very far apart compared to liquids and solids. This allows gas molecules to move freely and quickly, leading to high speeds. Gas can also be compressed because the molecules have more space between them, allowing for closer packing under pressure.
Do the molecules in a liquid all have about the same speed or is there a wide varity of speeds?
In a liquid, molecules have a wide range of speeds due to their random motion. The distribution of speeds follows a Maxwell-Boltzmann distribution, where most molecules have speeds around the average, but some have significantly higher or lower speeds.
Does evaporation speed up or slow down molecules?
Evaporation speeds up molecules. When a liquid evaporates, molecules at the surface gain enough energy to overcome intermolecular forces and escape into the surrounding air as a gas. This process results in the faster-moving molecules leaving the liquid, causing the average kinetic energy and speed of the remaining molecules to decrease, which leads to cooling of the liquid.
How fast are molecules in the air moving?
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.

Are cars affected by aerodynamics at low speeds?
It would depend on what you call low speeds.
do bromine molecules move faster then air molecules?
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.
What molecules speeds up chemical reactions by lowering activation?
Enzymes are the molecules that speed up chemical reactions, and these are forms of catalysts.
Which type of control agent never speeds an enzyme's action?
Substrate analog
When things are heated up where do the molecules move?
They don't necessarily move to another place. However, the movement of the molecules INSIDE the object speeds up. (:
Is police radar distorted by rain?
NO. It is only affected by a reduction in range or it will completely stop showing speeds.
How does wind affect the evaporation of water?
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
Does evaporation speed up or slow down molecules?
Evaporation speeds up molecules. When a liquid evaporates, molecules at the surface gain enough energy to overcome intermolecular forces and escape into the surrounding air as a gas. This process results in the faster-moving molecules leaving the liquid, causing the average kinetic energy and speed of the remaining molecules to decrease, which leads to cooling of the liquid.
Why would you not expect all of the molecules of air in your room to have the same average speed?
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.
