GGR214H5 Chapter Notes - Chapter 3: Ideal Gas Law, Gas Constant, Dynamic Pressure
Document Summary
In gases, temperature, pressure and density are related by the ideal gas law. This law allows us to predict how the atmosphere will respond to a change in one or more of the state variables. Hydrostatic balance tells us that the change in pressure with height or depth in a fluid is dependent on the density of the fluid. The kinetic theory of matter tells us that the differences between gases, liquids and solids begin at molecular level. Temperature is a measure of the average kinetic energy of molecules. We can use this theory to account for the differences between the three phases of matter. Gases: molecules are strongly attracted to each other, attraction is binding; can vibrate but not move freely, molecules are weakly attracted to each other, more freedom of movement, attraction is very small, molecules are free to move independently.
