Question

Which substance takes less heat energy to raise its temperature 1°C: 25 g (-1 oz) of freshwater, or 25 g of pure copper with a heat capacity of 0.092 cal/gCº? O freshwater O copper

Answer 1

ΔQ = M ρ ΔT heat required to change temperature of substance

Since ρ for copper is much smaller than ρ for water the heat energy is accordingly less for copper than for water
