The kinetic molecular theory makes it easy to see why a gas should exert a pressure on the walls of a container. Any surface in contact with the gas is constantly bombarded by the molecules. At each collision, a molecule moving with momentum mv strikes the surface. Since the collisions are elastic, the molecule bounces back with the same velocity in the opposite direction. This change in velocity ΔV is equivalent to an acceleration a; according to Newton's second law, a force f = ma is thus exerted on the surface of area A exerting a pressure P = f/A.
What else can I help you with?
Which gas will diffuse faster methane or carbon dioxide?
Helium diffuses twice faster as Methane does.
Which gas will diffuse faster between bromine and chlorine and why?
Chlorine gas will diffuse faster than bromine gas because it has a lower molecular weight and therefore moves more quickly through a medium. The rate of diffusion is inversely proportional to the square root of the molar mass of the gas, so lighter gases diffuse faster.
Is chlorine less dense or more dense than water?
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
Does water diffuse towards the area with more water or less water?
diffuse towards area with more water . diffusion happens where it is from higher concentration to lower concentration . so more water of course higher concentration , less water of course lower concentration . this is what i think . but don guarantee correct answer .
Is ammonia more dense or less dense than air?
Ammonia is less dense than air at room temperature and pressure. This is why ammonia gas rises in air.
Does more dense or less dense objects settle faster?
More dense objects settle faster than less dense objects. This is because denser objects have more mass and therefore experience a greater force of gravity pulling them downward, causing them to settle more quickly than less dense objects.
Why does less dense wood burn faster?
more space for air (oxygen)
Is diffusion more rapid for a molecule in a more or less dense media?
Diffusion is more rapid in less dense medias. Molecules have more open space that way and can move faster and more freely.
Why is the molasses going faster it is heated?
Warmer things are less dense, so as the molasses gets warmer, it becomes less dense or more "liquidy."
Why does gases diffuse more rapidly then liquid?
Gases diffuse more rapidly than liquids because gas molecules are less dense, have higher kinetic energy, and are not as tightly packed together as liquid molecules. This means that gas molecules can move more freely and quickly between particles, allowing for faster diffusion rates compared to liquids.
Would the density in liquid become more dense or less dense when thermal energy is added?
When thermal energy is added to a liquid, the molecules will move faster and further apart, causing the liquid to expand and become less dense.
Would liquid bromine diffuse more or less quickly than gaseous bromine after pouring it into another liquid?
Liquid bromine would diffuse more slowly than gaseous bromine when poured into another liquid. Diffusion occurs more readily in gases and in liquids, but since bromine is more dense in its liquid state, it will diffuse at a slower rate compared to when it is in its gaseous state.
Is ice less dense or more dense than water?
no
If the volume of air is less then the less dense or more dense the air is?
its has more pressure
How does destiny effect sound?
I assume you meant "density" More dense materials, such as solids, generally carry sound faster than less dense materials such as air
Is hot water less dense than cold water?
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
Is very salty water more or less dense than more dense?
More Dense.
