When 2.8 J of heat are added to 5.6 g of an unknown metal, its temperature rises by 3.9 °C. Are these data consistent with the metal being gold?

Solution 86P

∆H = m Cp ∆T

Rearranging the above equation,

Cp= ∆H / (m ∆T)

Where

Cp = specific heat capacity

∆H = heat added = 2.8 J

m = mass = 5.6 g

∆T = 3.9 °C

Substituting the above values, the equation will be

Cp = 2.8 J / (5.6 g 3.9°C)...
