from gay-lussac's law, If you increase the temperature of a gas (with constant moles and volume) what do you expect will happen to the pressure? Look up Boyle's Law. For an ideal gas at constant temperature and moles, if you increase the volume of the gas what do you expect will happen to the pressure of the gas? How else is the pressure-volume relationship typically plotted?

Calculate the gas constant, R O Convert your measured temperature to Kelvin and record it in your Notebook. Using the table found under "Resources," determine the vapor pressure of water at your measured temperature. Record the water vapor pressure in your Notebook. Calculate the pressure of hydrogen gas produced from your reaction. This will be the difference between the atmospheric pressure and the vapor pressure of water at your measured temperature. Record the hydrogen gas pressure in your Notebook. For...

Combined Gas Relationship Since the Ideal Gas Law produces a constant (R), it can be used to look at a gas sample in which initial and final conditions have changed. The combined gas relationship is as follows P.V R=P.V2 n, T n2 T2 where P, Vi,and T, and n, are the initial pressure, volume, temperature, and number of moles of gas. The final conditions are represented by P, V2, T2 and n2. If any of the conditions in the initial...
