What is the specific heat capacity of copper metal if 25.00 g loses 18 °C, when the metal is placed in 15 g of water and the water temperature rises 2.8 °C?

The specific heat capacity of copper metal : 0.390 J/g °C

Given

25 g metal

Δt metal = 18°C

15 g water

Δt water = 2.8 °C

Required

The specific heat capacity of copper metal

Solution

Q out = Q in

Q releases by metal = Q absorbed by water

m.c.Δt metal = m.c.Δt water(c water = 4.184 J/g °C)

25 x c x 18 = 15 x 4.18 x 2.8

c = 0.390  J/g °C
