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