Determine which law is appropriate for solving the following problem. What volume will 1.56 liters of a gas at 27^circ C and 745 mm Hg of pressure occupy at 100^circ C and 700 mm Hg of pressure? Law use square Charles' Law Combined Gas Law

To determine which law is appropriate for solving the problem, we need to consider the variables involved: volume, temperature, and pressure. <br /><br />Charles' Law relates volume and temperature at constant pressure, but in this problem, both temperature and pressure are changing. Therefore, Charles' Law is not suitable.<br /><br />The Combined Gas Law, on the other hand, relates pressure, volume, and temperature, making it applicable when all three variables change. The formula for the Combined Gas Law is:<br /><br />\[<br />\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}<br />\]<br /><br />where:<br />- \( P_1 \) and \( P_2 \) are the initial and final pressures,<br />- \( V_1 \) and \( V_2 \) are the initial and final volumes,<br />- \( T_1 \) and \( T_2 \) are the initial and final temperatures in Kelvin.<br /><br />Given that both temperature and pressure change in this problem, the appropriate law to use is the Combined Gas Law.
