Suppose there is Avogadro's number of mini marshmallows and they are used to cover the province of New Brunswick,
which has a land area of 7.145 x 104 km². Each mini marshmallow has a diameter of 0.635 cm and a height of 2.54 cm.
Assuming the marshmallows are packed together so there is no space between them, to what height above the surface, in
kilometers, will the mini marshmallows extend?

it should be p1 v1 = p2 v2

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.
