The constant motion of air molecules cause?
air pressure
Are molecules in the air part of the hydrosphere?
The water molecules are.
Why is Americium-241 used in smoke detectors?
Americium-241 is a radioactive isotope and used in smoke detectors to ionize the air (gives air molecules a charge). This allows a small current t flow between two contacts placed in the air chamber. When smoke particles enter the chamber, they attach themselves to the ionized molecules (by electrostatic attraction) effectively making them bigger and slowing the current. The detector then goes off when the current slows.
Air pressure becomes lower as water molecules are added to the air because water molecules .?
have less weight
When water molecules are moving closer together in the air is called?
When water molecules are moving closer together in the air it is called
How molecules in the air cause air resistance?
How molecules in the air cause air resistance?
How do molecules in air cause air resistance?
Molecules get in the way. When something passes through the air, it has to move molecules out of the way, and they are usually pushed aside.
The constant motion of air molecules cause?
air pressure
Air pressure is affected by temperature.?
Yes, air pressure is affected by temperature.When the temperature is higher the air pressure lowers and the weight of the air is lower. When air is warmer the molecules sperate and there are less molecules that can cause pressure.
Describe why a charged electroscope will discharge when placed near a radioactive material?
1. Electroscopes can be used to detect electronic charges and when a electroscope is given negative charges they repel each other and spread apart. They will remain apart until their electrons have somewhere to go and it combines with positive charges. When nuclear radiation is moving through the air it can remove electrons from some molecules In the air and cause other molecules in the air to gain electrons. - B0N3S

The friction between the ground and molecules in the air cause the wind to be what?
it will be slower near the surface
Does a cold front cause heavy precipitation?
When air gets colder, the molecules move closer together. The space between the molecules of air is where water particles stay when they are in clouds or in the air you breathe. So, when the space between molecules shrinks because of colder weather, the water molecules are "squeezed out" of the air and form into precipitation that then falls to the ground.
How molecules in the air cause air resistance in f1 cars travelling at high speed?

How are the speeds of molecules of air affected when the air is compressed by the action of a tire pump?
When air is pumped into a tire at great speed, there is an increase in the temperature of the air. This is because the fast compressions cause the air molecules to move, whereas they remain still during a slow compression.
When energy transfer to air what happens to the particles of air?
When energy is transferred to air, the molecules in the air become more excited. The energy causes the molecules to move around more than they did before, which could cause an increase in temperature, among other things.
