A gas consists of particles, which are either atoms or molecules, which all move randomly, and independently of each other. Every time a particle bounces off the wall of a container, it exerts some degree of pressure. The total of all the particles bouncing off the walls creates the pressure that we observe.
What else can I help you with?
Do gases exert pressure?
Yes. Any sample of gas in a closed container will exert pressure on the container, as long as the temperature of the gas is above absolute zero. You can force the gas into a smaller volume by shrinking the container, but that action raises the temperature and pressure of the gas.
Is the pressure exerted by different gases different?
Yes, the pressure exerted by different gases can be different, as it depends on factors such as the number of gas molecules, temperature, and volume. However, if the gases are in the same container at the same temperature, they will exert the same pressure.
What are the six properties of gases?
Gases have no fixed shape or volume. They expand to fill the container they are in. They are compressible. Gases have low density compared to liquids and solids. They exert pressure on the walls of their container. Gases are highly mobile and can diffuse rapidly.
Why Gases unlike solids and liquids exert pressure in all directions?
Gases have no fixed shape or volume, allowing their molecules to move freely and fill the entire space available to them. As a result, gas molecules collide with the walls of their container in all directions, exerting pressure uniformly in all directions. In contrast, solids and liquids have fixed shapes and volumes and thus exert pressure in a more localized manner.
Why do gases exert more pressure on the walls of a container than a solid?
Pressure is given by kinetic theory of gases as P = 1/3 rho C^2 Here rho is the density and C is the root means square value of velocity of molecules In case of gas C is large but in solid C is almost zero
What is the volume that you can fill by evaporating one ounce of helium liquid?
It will fill any container you evaporate it into, and still exert pressure on the inside of the container in its relentless quest for more volume. That's just what gases do.
Do gases exert pressure?
Yes. Any sample of gas in a closed container will exert pressure on the container, as long as the temperature of the gas is above absolute zero. You can force the gas into a smaller volume by shrinking the container, but that action raises the temperature and pressure of the gas.
Why gases exert equal pressure in all directions?
Gases exert equal pressure in all directions because gas particles are in constant random motion, colliding with each other and the walls of the container. These collisions result in pressure that is evenly distributed in all directions within the container due to the kinetic energy of the gas particles.
Is the pressure exerted by different gases different?
Yes, the pressure exerted by different gases can be different, as it depends on factors such as the number of gas molecules, temperature, and volume. However, if the gases are in the same container at the same temperature, they will exert the same pressure.
What is exerted by gases by molecular movement?
Gases exert pressure by colliding with the walls of their container due to the random motion of their molecules. This constant bombardment of the container walls creates pressure, which is a measure of the force per unit area exerted by the gas molecules.
How will you explain the fact that gases exert pressure on all surfaces of the container?
Atoms in a gas move about randomly, and some will bounce against every surface of the container.
How do gas particles exert pressure on their container?
'This is because the air particles are bumpinginto each other and the walls. When this happens it causes pressure on the walls because of the speed the air particles are moving
How the air particles exert a pressure on the inside of the balloon?
Particles in gases, like the gas inside the balloon, move around a lot, fill up their container and collide a lot, both with each other and the walls of the container (ie - the balloon). Pressure is just how many collisions there are. So high pressure is when the particles collide with the walls of the container loads, and low pressure is when they don't collide with it very much. So the gaseous particles collide with the inside of the balloon, creating pressure. Hope that helps :)
What will happen to gases that are restricted to a contained environment?
It depends on the severity of the gases (farts) that determine the effects of the gases. For instance if the gases were restricted inside of a blanket then it would be considered a dutch oven. Also what was eaten has to ne taken in account.
How can you tell that the substance in the container is a gas?
If the substance takes the shape of its container, has no definite volume, and can be easily compressed, it is likely a gas. Additionally, gases typically exert pressure on the walls of their container and expand to fill the available space.
What are the six properties of gases?
Gases have no fixed shape or volume. They expand to fill the container they are in. They are compressible. Gases have low density compared to liquids and solids. They exert pressure on the walls of their container. Gases are highly mobile and can diffuse rapidly.
Give an example to explain how gas exert pressure.?
Its the fact that the gases have variable volume that makes the gas exert pressure in other words the number of collisons between the gas molecules and the walls of the container that is calculated as pressure(it is assumed the intermolecular collison are elastic this failed in case of the ideal gas which resulted in van der waall's pressure and volume correction to the ideal gas equation) the potential of this gas pressure can be observed by small experiment in which a slab of wood which is almost foot in thickness(i think 25 cms) was exposed to a pressure of nearly 90 ATM it was crushed to paper!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
