(b) Intensive and extensive properties: Intensive properties are properties that do not depend on the size or amount of the system being studied, while extensive properties do depend on the size or amount of the system.
(c) Substance and mixture: A substance is a pure chemical compound that cannot be separated into simpler components by physical means, while a mixture is a combination of two or more substances that can be separated by physical means.
(d) Systematic and random errors: Systematic errors are errors that occur consistently and can be attributed to a particular cause, while random errors are errors that occur randomly and cannot be attributed to a particular cause.
(e) Hypothesis and theory: A hypothesis is a proposed explanation for an observed phenomenon, while a theory is a well-supported and widely accepted explanation for a phenomenon based on extensive experimentation and observation..
