If the statement is true, write true. If it is false, change the underlined word to make it true. 6. The temperature at which a pure substance changes from the solid state to the liquid state
is called its boiling point.
7. If you move an object from place to place in the universe, the weight of the object will

8. Grams per milliliter (g/mL) is an example of a unit of volume.
9. One of Dalton's principles is that each element is made of its own kind of atom.
10. Useful amounts of copper can be isolated during a process called electrolysis.

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.
