Answer: Entropy is sometimes described as the degree of randomness in a system.
When one observes the phase of matter of water, one observes a physical property of matter.
Arrhenius theory is a theory about acids and bases. It says that acids are those substances that produces hydrogen ions (H+) when in solution and bases are the substances that dissiociates and produces hydroxide ions (OH-). It was introduced by Svante Arrhenius.
