Cold air has more molecules occupying a cubic centimeter of space than warm air therefore it has what kind of pressure?
higher
Is the pressure decrease or increase with altitude?
Pressure is due to the number of molecules hitting you or your instrument. As you go up in altitude, there are less molecules hitting you, i.e., the pressure decreases. The higher you go, you are getting thinner atmosphere, which means there are less molecules available, so the pressure is lower. Air molecules are more abundant closer to the surface, and therefore the molecules are closer together, i.e. higher pressure.
What makes the waterevaporate?
Water has a large vapor pressure compared to air. Water molecules therefore readily move into the air.
How many atoms are found in 9 molecules of nitrogen gas?
At standard temperature and pressure, nitrogen contains two atoms per molecule. Therefore 9 molecules contain 18 atoms.
How are molecules and air pressure connected?
Air pressure has molecules in it but other than that their is no connection

How many molecules are in 1 cubic centimeter of air?
The answer will depend on the temperature and pressure.
How does diffusion show that molecules are always moving?
How? Molecules move from an area of higher concentration to an area of lower concentration. When the concentration decreases (be it determines by a measure of pressure) in a unit volume; that indicates there are less molecules occupying that given space. So they must have gone somewhere...

Why does pressure increases when force is exerted?
If the temperature of the gas is increased, the average kinetic energy of its molecules increases. Therefore, the molecules hit the wall "harder" and also more frequently. The total force due to the collisions is greater. Therefore the pressure increases.
How the vapour pressure of ether is greater than the vapour pressure of water?
Water molecules are held together by hydrogen bonds which are relatively strong. Ether molecules do not have such intermolecular forces holding molecules together. Therefore, it is easier for ether molecules to escape as a vapor, and this is why the vapor pressure of ether is greater than that of water.
What causes pressure?
The weight of the air The distance between particles of a gas determines the pressure. The distance can be decreased and the pressure therefore increased by either increasing the amount of particles of gas in the container, or by reducing the size of the container.

What is it about warm gas molecules that give them higher gas pressure than cool gas molecules?
Warmer molecules have more energy, and therefore move faster. Gas molecules will collide with solid objects, these collisions are what cause gas to have a pressure in the first place. Faster molecules mean more energetic collisions, hence a higher pressure on their surroundings. In the case of a sealed vessel, that means that when the temperature rises high enough, the molecules collide with it with enough force to rupture the vessel and burst it open.
What creates pressure in a bicycle tire?
The pressure increases, and the molecules collide with the tire's inner surface.
