Explanation

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

Brass: 95.0 °C;Water: 25.0 °C.

How much energy did water gain in this process?

Heat capacity c: 4.18 J · g⁻¹ · °C⁻¹;Mass of water m: 335 g;Temperature change ΔT: 32.0 - 25.0 = 7.0 °C.

.

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?

Heat capacity of brass is to be found;Mass of the cylinder: 410 g;Temperature change: 95.0 - 32.0 = 63.0 °C.
