Determine which law is appropriate for solving the following problem. What temperature will 215 mL of a gas at 20^circ C and 1 atm pressure attain when it is subject to 1.5 atm of pressure? Law use square Combined Gas Law Charles's Law

To determine which law is appropriate for solving the problem, we need to consider the variables involved:<br /><br />- Initial and final pressures are given (1 atm and 1.5 atm).<br />- Initial volume is given (215 mL), but the final volume is not mentioned.<br />- Initial temperature is given ($20^{\circ}C$), and we need to find the final temperature.<br /><br />Since both pressure and temperature are changing while the volume remains constant, the Combined Gas Law is the most appropriate choice. The Combined Gas Law relates pressure, volume, and temperature of a gas and is expressed as:<br /><br />\[<br />\frac{P_1 \cdot V_1}{T_1} = \frac{P_2 \cdot V_2}{T_2}<br />\]<br /><br />However, since the volume is constant in this scenario, it simplifies to:<br /><br />\[<br />\frac{P_1}{T_1} = \frac{P_2}{T_2}<br />\]<br /><br />Therefore, the appropriate law to use is the Combined Gas Law.
