Q1. If there were some dirt on your 50 mL beaker that was not removed before you began the experiment, it is important to understand how it would affect your mass measurements and your density
result. Would the masses be high, low or unchanged by the dirt? Would the density be high, low or
unchanged by the dirt? Explain your answer.

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.
