Wat sal die ewewigstemperatuur wees wanneer ’n 245 g blok koper by 285°C in ’n 145 g aluminium-kalorimeterbeker geplaas word wat 825 g water by 12.0°C bevat?

Die spesifieke hitte van koper en aluminium is onderskeidelik 390 J kg⁻¹ K⁻¹ en 900 J kg⁻¹ K⁻¹.

What will be the equilibrium temperature when a 245-g block of copper at 285°C is placed in a 145-g aluminum calorimeter cup containing 825 g of water at 12.0°C?

The specific heat of copper and aluminum are 390 J kg⁻¹ K⁻¹ en 900 J kg⁻¹ K⁻¹., respectively.
