Gas law - Essay Example The independent variable in this chart is temperature whereas the dependent variable is volume. This corresponds to Charles law V/T = k From figure 3, it is seen that the volume of a gas decreases exponentially with the increase in pressure. Plotting the values of pressure against the inverse of the volume gives us Boyles law (PV = Constant) that states that at constant temperature the pressure of the gas is inversely proportional to the size. From the figure for it is observed that when the pressure is doubled the volume is reduced by half. The linear graph passes through the point of origin (0, 0). Air is a mixture of different gases that respond differently in different conditions. The ideal gas law provides provisions for incorporation of various gasses in a system. Therefore, air was a suitable choice for an ideal gas According to the ideal gas law PV=nRT, therefore at constant number of moles and temperature the pressure is inversely proportional to the volume and therefore obeys Boyles law. At constant n and P, V is directly proportional to T with increasing T, V will also increase. From the data calculated and represented in figures 1-3 the ideal gas law is experimentally defined. From figure 1, it has been seen that the volume is directly proportional to temperature at constant pressure. From figure 2 it is observed that the volume is directly proportional to temperature and from figure 3 and 4 it is observed that the volume is inversely proportional to pressure. All these are the ideas behind the ideal gas
