A gas in a container will escape through holes of microscopic size, as long as the holes are larger than the gas molecules. This process called effusion. If a gas of molar mass M_1 effuses at a rate of r_1 and a gas of molar mass M_2 effuses at a rate of r_2, then the ...
The larger the volume of the individual molecules of a gas, the more that gas behaves like an ideal gas. True False True or false? Molecules of a gas undergo many collisions with each other and the container walls. Real gases behave like ideal gases over a wide range of...
For a countermeasure, a simple operation prevents hydrogen molecules, helium gas, and volatile component from scattering and being lost. A container filled with gas, or liquid or viscous fluid in which gas is dissolved, or metal granules adsorbing gas is given a cap, and then, the whole of ...
15 When molecules of a gas rebound from a wall of a container, the wall experiences a pressure.What is the cause of this pressure? B A the change in energy of the molecules B the change in momentum of the molecules C the change in power of the molecules D the change in speed of t...
14 A gas is heated in a sealed container.The volume of the container does not change.What happens to the molecules of the gas? B A The average distance between molecules increases. B The average kinetic energy of the molecules increases. C The mass of each molecule increases. D The volume...
15 A fixed mass of gas is trapped in a container. The temperature of the gas is increased but the volume of the gas is kept constant.fixed mass of gas How does this change affect the kinetic energy of the molecules and the pressure on the walls of the container?A kinetic energy pressur...
10 A quantity of gas is trapped in a container by a piston exerting a force F The temperature of the gas is raised while F remains unchanged.Which statement is correct? A A The gas expands B The molecules get larger C The piston remains in the same place D The speed of the molecules...

4 (a) Explain, in terms of molecules, how a gas causes a pressure on the walls of its container.[4] (b) Complete the following two sentences.(i) At constant temperature, the pressure of a gas increases as its volume(ii) At constant volume, the pressure of a gas increases as its ...
Gas molecules are always in constant, rapid, and random motion and as a result, have a large amount of kinetic energy (energy of motion). As the particles move around, they collide with each other and with the container that they are in. This is what causes gas pressure. Gases will ...
