1. Using Boyle's Law, which states that the volume of a gas is inversely proportional to its pressure when temperature is held constant, we can calculate the new volume of the gas when the pressure changes. The formula is P1V1 = P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume. Plugging in the given values, we get 5 atm * 14 L = 4 atm * V2. Solving for V2, we get V2 = 17.5 L.2. Using Boyle's Law again, we can calculate the new volume of the gas when the pressure changes. Plugging in the given values, we get 10 atm * 24 L = 7 atm * V2. Solving for V2, we get V2 = 34.29 L.3. Using Boyle's Law, we can calculate the new volume of the gas when the pressure changes. Plugging in the given values, we get 7 atm * 23 L = 4 atm * V2. Solving for V2, we get V2 = 41.25 L.4. Using Gay-Lussac's Law, which states that the pressure of a gas is directly proportional to its temperature when volume is held constant, we can calculate the new pressure of the gas when the temperature changes. The formula is P1/T1 = P2/T2, where P1 and T1 are the initial pressure and temperature, and P2 and T2 are the final pressure and temperature. Plugging in the given values, we get 1 atm / (273.15 + 20) K = P2 / (273.15 + 125) K. Solving for P2, we get P2 = 1.47 atm.5. Using Gay-Lussac's Law, we can calculate the new pressure of the gas when the temperature changes. Plugging in the given values, we get 2 atm / 320 K = P2 / 470 K. Solving for P2, we get P2 = 2.94 atm.6. Using Charles's Law, which states that the volume of a gas is directly proportional to its temperature when pressure is held constant, we can calculate the new volume of the gas when the temperature changes. The formula is V1/T1 = V2/T2, where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature. Plugging in the given values, we get 500 mL / (273.15 + 57) K = V2 / (273.15 + 127) K. Solving for V2, we get V2 = 805.56 mL.7. Using Gay-Lussac's Law, we can calculate the new pressure of the gas when the temperature changes. Plugging in the given values, we get 1.5 atm / (273.15 + 15) K = P2 / (273.15 + 100) K. Solving for P2, we get P2 = 2.04 atm.8. Using Boyle's Law, we can calculate the new volume of the gas when the pressure changes. Plugging in the given values, we get 2 atm * 9 L = 1 atm * V2. Solving for V2, we get V2 = 18 L.9. Using Boyle's Law, we can calculate the new pressure of the gas when the volume changes. Plugging in the given values, we get 3 atm * 15 L = P2 * 12 L. Solving for P2, we get P2 = 3.75 atm.10. Using Charles's Law, we can calculate the new temperature of the gas when the volume changes. Plugging in the given values, we get 16 L / (273.15 + 112) K = 25 L / T2. Solving for T2, we get T2 = 343.15 K.11. Using Charles's Law, we can calculate the new temperature of the gas when the volume changes. Plugging in the given values, we get 12 L / 260 K = 3 L / T2. Solving for T2, we get T2 = 39.23 K.12. Using Charles's Law, we can calculate the new volume of the gas when the temperature changes. Plugging in the given values, we get 9 L / (273.15 + 1) K = V2 / (273.15 + 125) K. Solving for V2, we get V2 = 11.11 L.13. Using Charles's Law, we can calculate the new volume of the gas when the temperature changes. Plugging in the given values, we get 6 L / 262 K =
