I like to put ice (c= 2.11 J/gC) in my coffee to cool it down. If the temperature of the ice I get out of my refrigerator is at 2°C and drop it into 100g of hot coffee at 80°C (c = 4.18 J/g°C).
How much ice would I need to use if I want the ending temperature to be 50°C?
*make sure to include the units on your answer

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.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
