Define chemistry. a) chemistry is the science of matter and its motion, as well as space and time - the science that deals with concepts such as force, energy, mass, and charge. b) chemistry is the science that seeks to understand what matter does by studying what atoms and molecules do. c) chemistry is the science that studies the molecular transformations only in nonliving matter. d) chemistry is the science that studies the molecular transformations only in living matter.

The correct answer is option B) "Chemistry is the science that seeks to understand what matter does by studying what atoms and molecules do".

Explanation:

Chemistry is a branch of science that deals with the study of matter, the properties that defines it and how it interacts with other matter and energy. Basically, chemistry is the science that seeks to understand what matter does by studying what atoms and molecules do. The basic premise of chemistry is that by dissecting matter and studying its components, we will be able to understand how it behaves and the reactions we see in nature.

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.
