WitrynaBecause most of the volume occupied by a gas is empty space, a gas has a low density and can expand or contract under the appropriate influence. The fact that gas particles are in constant motion means that two or more gases will always mix as the particles from the individual gases move and collide with each other. WitrynaHere's a chemistry project for a beginning scientist. You'll need two 100 ml graduated cylinders, rubbing alcohol, water and liquid food dye. (You can make your own …

WitrynaThe term ideal gas refers to a hypothetical gas composed of molecules which follow a few rules: Ideal gas molecules do not attract or repel each other. The only interaction between ideal gas molecules would … WitrynaIt helps to remember that the volume we use in the ideal gas equation is the empty volume that the gas molecules have to move around in. We usually assume that this is the same as the volume of the container when the gas molecules don’t take up much space. But what happens when this is not the case, such as at high pressures?
