Weba) Compare a solid and a gas with respect to the arrangement of their molecules. Use this comparison to explain how solids exert pressure and how gases exert pressure. b) Describe condensation (the change from gas to liquid) in terms of the kinetic molecular theory (KMT). c) Explain, using the KMT, why a gas is compressible and a liquid is not. WebThe pressure exerted by a gas is due to the random motion of particles in the gas. Gases have weak intermolecular forces and the particles are in continuous random motion and these particles collide with the walls of the container. These collisions with the walls of the container exert pressure on the gas. 66 views Sponsored by Brainable

WebJun 7, 2024 · Jun 7, 2024. In the kinetic theory of gases, gas molecules move around in the most random way colliding and bumping into each other and then bouncing off in the opposite direction. The molecules exert no intermolecular forces on each other and they have no potential energy associated with them in their motion. Thus the energy is wholly … WebPressure is defined as the force exerted divided by the area over which the force is exerted.

WebOn the basis of kinetic theory of gases, the gas exerts pressure because its molecules A suffer a change in momentum when impinging on the walls of the container. B continuously stick to the walls of the container. C continuously lose their energy till it reaches the wall. D are attracted by the walls of the container. Solution WebMar 4, 2024 · We begin by recalling that the pressure of a gas arises from the force exerted when molecules collide with the walls of the container. This force can be found from Newton's law (2.6.2) f = m a = m d v d t in which v is the velocity component of the molecule in the direction perpendicular to the wall and m is its mass. WebWhen a molecule collides with the wall, they exert small force on the wall. The pressure exerted by the gas is due to sum of all these collision forces with the wall of container. The more the particles hit the wall, the higher the pressure. Therefore, due to gaseous molecules collides in air gases exert pressure. Suggest Corrections 11 detmeir grocery store

WebSep 17, 2024 · Because as we compress the, the gas particles prevent each other from occupying the same volume. So if volume increases, it should be exerting more pressure … WebGas Pressure Pressure is defined as the force per unit area on a surface. When a person stands on the floor, his feet exert pressure on the surface. That pressure is related to both the mass of the person and the surface area of his feet. If the person were holding a heavy object, the pressure would increase churchartpro.comWebJul 21, 2024 · pressure = force area All gases exert pressure; it is one of the fundamental measurable quantities of this phase of matter. Even our atmosphere exerts pressure—in this case, the gas is being “held in” by the earth’s gravity, rather than the gas being in a container. church arrangements/floral

WebNov 5, 2015 · The ideal gas equation (or the van der Waals equation, for this matter) states that holding volume and temperature constant, increasing the number of moles of particles in the container will increase the total pressure exerted by the gas mixture. WebOct 17, 2015 · For an ideal gas, you have a relationship for the pressure that looks like the following: P = N k B T V where N is the number of particles, k B is a constant, T is the temperature and V is the volume of the container. In this case, you have a constant pressure on all the walls of a container.

WebJan 12, 2015 · In evaporation, molecules escape from the liquid's surface and become a gas. Molecules in the liquid are in constant motion, and they frequently collide with each other. Every now and then one will get knocked off the surface of the liquid by the others. This can happen at any temperature or pressure the liquid exists at. WebThe pressure of any gas can be calculated using the formula given by,$PV=nRT$Where P is the pressure exerted on the gas V is the volume of the container n is the amount of gas R …

WebJan 28, 2014 · If they hit the surface of the balloon straight on (at a 90 ° angle), they exert their maximum force. If they hit the surface at an angle less than 90 °, they exert a smaller force. The sum of all these forces causes the pressure, p, that is exerted by the gas. The diagram above represents a balloon containing molecules of a gas (the red dots). WebAs a result, the gas particles hit the walls of the container in which it is kept, at high speeds. The particles can also hit each other. The pressure exerted by the gas is because of the …

WebApr 18, 2024 · How does gas in a container exert pressure to the walls of the container Postulate #3? The pressure exerted by a gas in a container results from collisions between the gas molecules and the container walls.
