The society of automotive engineers has established an accepted numerical scale to measure the viscosity of motor oil. for example, sae 40 motor oil has a higher viscosity than an sae 10 oil. rank the following hydrocarbons by their expected viscosity.

let that person have a turn to speak : )

just did the assignment and the answer was #1 +2 n

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.
