Find more answers. Previously Viewed. If there weren't any air molecules at all there wouldn't be any pressure. Pressure is directly proportional to N - an increase in N causes an increase in P. If N doubles, P also doubles as long as the other variables in the equation don't change.
In B Air pressure inside a balloon also depends on the size of the balloon. Pressure is inversely proportional to volume, V. Note It is possible to keep pressure constant by changing N and V together in just the right kind of way. This is what happens in the oxygen concentration experiment described in Week 1. Oxygen in a graduated cylinder reacts with steel wool to form rust. Oxygen is removed from the air sample which is a decrease in N. As oxygen is removed, water rises up into the cylinder decreasing the air sample volume.
N and V both decrease in the same relative amounts and the air sample pressure remains constant. Part C : Increasing the temperature of the gas in a balloon will cause the gas molecules to move more quickly. They'll collide with the walls of the balloon more frequently and rebound with greater force. Both will increase the pressure. You shouldn't throw a can of spray paint into a fire because the temperature will cause the pressure inside the can to increase and the can could explode.
We'll demonstrate the effect of temperature on pressure in class on Friday. Surprisingly, as explained in Part D , the pressure does not depend on the mass of the molecules.
Pressure doesn't depend on the composition of the gas. Gas molecules with a lot of mass will move slowly, the less massive molecules will move more quickly. They both will collide with the walls of the container with the same force. The figure below shows two forms of the ideal gas law. The top equation is the one we just derived and the bottom is a second slightly different version.
You can ignore the constants k and R if you are just trying to understand how a change in one of the variables would affect the pressure. You only need the constants when you are doing a calculation involving numbers which we won't be doing. Air in the atmosphere behaves like air in a balloon. A balloon can grow or shrink in size depending on the pressure of the air inside. When a balloon isn't getting bigger or smaller it means the force inside that is pushing out is balanced by the force outside that is pushing in.
We start in the top figure with air inside a balloon that is exactly the same as the air outside. The air inside and outside have been colored green. What is inside the inflated balloon? Why does a helium balloon float up when it is released? How can you use helium?

The floating bubbles unfortunately seldom last long enough for this to be seen. The sublimation of dry ice is worth pointing out here. A small lump left on the desk will disappear without melting, although it may become covered in some ice. This collection of over practical activities demonstrates a wide range of chemical concepts and processes.
Each activity contains comprehensive information for teachers and technicians, including full technical notes and step-by-step procedures.
Use this practical to investigate how solutions of the halogens inhibit the growth of bacteria and which is most effective.
