The gas in the piston is being heated, and the piston has moved upward. The observation will be summarized in a row of the incomplete table below. A container with a piston inside it. An arrow above the piston points upward. Row Name Observation Variables 1 Boyle's law Volume increases when pressure decreases ? 2 Charles’s law ? ? 3 Gay-Lussac’s law ? Temperature, pressure 4 Combined gas law ? ? What are the variables for this piston? temperature only temperature and volume pressure and number of molecules volume and number of molecules.

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.

you need to have a picture of the atom that way we can answer it
