Why is it important to record and organize scientific data from investigations?

The 'systematic' part is important because science is all about doing investigations in a certain way to reduce the bias that all humans have and make the results as accurate and useful as possible. Once you've done your investigation, it comes time to communicate those findings to the scientific community.

Explanation:

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
