What are the difference between a red giant and a red super giant

Red giants are very large stars which are highly luminous and have an inflated outer surface with an approximate temperature of about 5000 degrees K or lower.

Whereas, Red supergiants are the largest stars in the whole universe in terms of volume but they are simply bright, red stars unlike the red giants.

Having said that, there are no agreed theoretical distinctions between the red giants and red supergiants so there is still a room for confusion to discriminate between the two.

step-by-step explanation:

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.
