• Boyle's Law: For a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. Mathematically, P (1)/(V) or PV = constant.

Here are the solutions to your questions. 1) • Boyle's Law: For a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. Mathematically, P (1)/(V) or PV = constant. • Charles' Law: For a fixed mass of gas at constant pressure, the volume of the gas is directly proportional to its absolute temperature. Mathematically, V T or (V)/(T) = constant. • Pressure Law (also known as Gay-Lussac's Law): For a fixed mass of gas at constant volume, the pressure of the gas is directly proportional to its absolute temperature. Mathematically, P T or (P)/(T) = constant. 2) To calculate the pressure exerted by the gas and state the General Gas Equation: Step 1: Convert the given temperatures from Celsius to Kelvin. T_1 = 27^ + 273 = 300 K T_2 = 90^ + 273 = 363 K Step 2: Identify the given initial pressure. P_1 = 80 mmHg Step 3: Since the volume is maintained at constant, we use the Pressure Law (Gay-Lussac's Law), which states that (P_1)/(T_1) = (P_2)/(T_2). Rearrange to solve for P_2. P_2 = P_1 × (T_2)/(T_1) Step 4: Substitute the values and calculate the final pressure. P_2 = 80 mmHg × 363 K300 K P_2 = 80 × 1.21 mmHg P_2 = 96.8 mmHg The pressure exerted by the gas is 96.8 mmHg. Step 5: State the General Gas Equation. The General Gas Equation combines Boyle's Law, Charles' Law, and the Pressure Law. It is given by: (P_1 V_1)/(T_1) = (P_2 V_2)/(T_2) Send me the next one 📸
