GAS LAWS

• Boyle's Law - states that the pressure and volume are inversely proportional at constant temperature
• The two measurable variables in Boyle's law are: Volume and Pressure
• The constant in Boyle's law is the temperature
• The formula for Boyle's law is - P1V1 = P2V2
• The constant in Charles' law is the pressure
• Charles' Law - states that the volume is directly proportional to the temperature at constant pressure.
• In Boyle's law, as the pressure increases, the volume decreases.
• The two measurable variables in Charles' law are: Volume and Temperature
• The two measurable variables in Gay-Lussac's law are: Pressure and Temperature
• Gay-Lussac's Law - states that the pressure is directly proportional to the absolute temperature at constant volume.
• The formula in Charles' law - V1/T1 = V2/T2
• The absolute zero has a value of -273.15 degrees celsius
• In Charles' law, as the volume increases, the temperature also increases
• In Charles' law, as the balloon is heated, it will expand. And as the balloon is cooled, it will shrink.
• Universal unit for temperature is Kelvin.
• True or False. Always convert the temperature from Celsius to Kelvin before substituting in the formula. True
• True or False. Always follow the highest significant figures of the given as your answer. True
• Gay-Lussac's Law - states that the pressure of an ideal gas is directly proportional to its temperature at constant volume.
• The formula in Gay-Lussac's law is - P1/T1 = P2/T2
• The constant in Gay-Lussac's law is the volume.
• An application of gay-lussac's gas law in real life situation is when using the pressure cooker.
• In Gay-Lussac's law, as the temperature goes up, the particles move at higher speed resulting in greater pressure.
• Combined Gas Law - states that the pressure and volume of a gas are inversely proportional to the absolute temperature of the gas at a constant amount of gas.
• The measurable variable in Combined Gas law are: Pressure, Volume, Temperature
• The formula in Combined Gas law - (P1) (V1) / (T1) = (P2) (V2) / (T2)
• An application of Combined Gas Law in real-life situation is the cloud formation.
• Avogadro's Law - states that the volume and number of moles are directly proportional at constant pressure and temperature.
• The symbol for number of moles is n
• In Avogadro's law, as the volume increases, the number of moles also increases
• The formula in Avogadro's law - V1/n1 = V2/n2
• In Avogadro's law, when the given is in chemical equation, the first thing to do is to balance the equation.
• In Avogadro's Law, after balancing the equation; use the formula - (given volume of reactant) (number of molecules of product)/ (number of molecules of reactant)
• In chemical equation, the coefficient is termed as the number of molecules.
• In chemical equation, the subscript is termed as number of atoms.
• The unit for pressure can be mmHg, atm, kPa, and others.
• Ideal Gas - does not undergo gas change
• Real Gas - undergoes gas change
• R is the gas constant in Ideal Gas Law
• In Ideal gas law, R has a value of 0.0821 atmL/molK
• Ideal gas law has a formula of PV=nRT
