What is the name for temperature changes which involve no heat transfer?

Adiabatic.

In thermodynamic chemistry, an adiabatic process is defined as the process in which there is no transfer of heat and mass takes place between system and surroundings. The energy will transfer only in the form of work. The condition is expressed as q=0, which means no heat is transferred. It has various applications in the study of thermodynamics reactions.

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.
