One of the physical properties of fuels that is relevant to use in a combustion engine is viscosity. the viscosities of diesel, biodiesel, and vegetable oil are very different from each other. why is viscosity an important property in this context? how does the viscosity of diesel compare to the viscosity of biodiesel? (hint: check out the "additional reading" links in last week's introduction section) why is the viscosity of biodiesel lower than the viscosity of vegetable oil?

put the answers   and i could 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.
