Daryl adds 100 mL of boiling water to 200 mL of ice water. If she then puts the 300 mL of water into a freezer, at what
temperature will the water freeze?

A. 15 C
B. 32 C
C. 0 C
D. 50 C

i'm assuming that the correct answer is indeed the first one/ "a"..

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.
