Which is an example of radiation? Troy’s hand is burned when he touches hot wax. Earth is heated by energy from the Sun. A hot dog is held over a fire and gets warm. Water is boiled in a pot on a stove burner.

the correct answer is:

a. formation of precipitation

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.
