The Law of Conservation of Mass states that the total mass of a closed system remains constant, regardless of the changes that occur within the system.

The Law of Conservation of Energy states that the total energy of a closed system remains constant, regardless of the changes that occur within the system.

The Law of Thermodynamics states that the entropy of a closed system always increases, or remains constant in the case of a reversible process.

Charles's Law states that the pressure of a gas is directly proportional to its temperature, when the volume of the gas is held constant.

Charles's Law states that the volume of a gas is directly proportional to its temperature, when the pressure of the gas is held constant.

Boyle's Law states that the pressure of a gas is inversely proportional to its volume, when the temperature of the gas is held constant.

Avogadro's Law states that the volume of a gas is directly proportional to the number of moles of gas, when the pressure and temperature of the gas are held constant.

Gay-Lussac's Law states that the pressure of a gas is directly proportional to the number of moles of gas, when the volume and temperature of the gas are held constant.

The Law of Mass Action states that the rate of a chemical reaction is directly proportional to the concentration of the reactants, raised to their respective stoichiometric coefficients.

The Arrhenius Equation states that the rate of a chemical reaction is directly proportional to the exponential of the negative activation energy divided by the temperature of the reaction.

Collision Theory states that the rate of a chemical reaction is directly proportional to the number of collisions between the reactants, and the fraction of those collisions that have enough energy to overcome the activation energy.

Transition State Theory states that the rate of a chemical reaction is directly proportional to the concentration of the transition state complex, which is the highest energy state that the reactants must pass through in order to form products.

The Law of Conservation of Energy states that the total energy of a closed system is conserved, meaning that it cannot be created or destroyed, only transferred or transformed.

The Law of Thermodynamics states that the entropy of a closed system always increases, or remains constant in the case of a reversible process.

Boyle's Law states that the pressure of a gas is inversely proportional to its volume, when the temperature of the gas is held constant.
