Verified step by step guidance

Understand the definition of a pure substance: A pure substance is a form of matter that has a constant composition and properties that are consistent throughout the sample.

Identify the characteristics of a pure substance: It consists of only one type of particle, such as atoms or molecules, and has a fixed composition.

Recognize that pure substances cannot be separated into components by physical means. This is a key characteristic that distinguishes pure substances from mixtures.

Analyze the given options: Determine which option does not align with the characteristics of a pure substance.

Conclude that the option 'Can be separated into components by physical means' is not a characteristic of a pure substance, as pure substances cannot be separated by physical methods like filtration or distillation.
