0.379 J · g⁻¹ · °C⁻¹.

Energy change Q = c · m · ΔT.

Temperature change ΔT = Final Temperature - Initial Temperature.

The final temperature of both brass and water is 32.0 °C. However, the two differ in initial temperature.

Initial temperature

How much energy did water gain in this process?

.

How much energy did brass lose in this process?

The brass cylinder is cooled in a calorimeter. The calorimeter traps heat inside, such that water absorbs all the heat lost from the brass.

.

What's the heat capacity of brass?

the answer would be c

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.
