What is the main difference between weather and climate? Weather is atmospheric events in a short time and climate is an average of weather events over a long period of time. Climate is atmospheric events in a short time and climate is an average of weather events over a long period of time. Nothing. They are the same.

the 1st choice Weather is atmospheric events in a short time ect

Explanation:

That's it

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.
