Relationship between Pressure, Temperature, Volume, and the amount of Gas Occupying an Enclosed Room - Essay Example

From figure 2, it is seen that at constant volume pressure of a gas increases proportionally with temperature. The independent variable is temperature whereas the dependent variable is pressure

From equation y= 0.003x+0.1111

X intercept =  = -37.033K

            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's law (PV = Constant) which states that at constant temperature the pressure of the gas is inversely proportional to the size. From the figure, 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 the incorporation of various gasses in a system. Therefore, the air was a suitable choice for an ideal gas

According to the ideal gas law PV=nRT, therefore at a 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.
