1. A sample of hydrogen has a volume of 25 L under a pressure of 5 atm. What will be the pressure of this gas if the volume is decreased by 1/5 L.? 2. If a gas occupies 312 at a pressure of 1.60 atm, what pressure is necessary for the gas to occupy a volume of 500 L?

have a great day because if you dont you and i will be sad

fe 55.85 g/mol and h2o 18.02 g/mol.

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.
