    • 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
