An unknown metal has a mass of 77.3 g. When 3610 J of heat are added to the sample, the sample temperature changes by 52.1 ∘C. Calculate the specific heat of the unknown metal. Metal Specific heat (J/g⋅∘C) aluminum 0.897 tin 0.210 strontium 0.301 barium 0.204 calcium 0.650 nickel 0.440

specific heat = .897 J /g°C

Explanation:

Quantity of heat added = mass x specific heat x rise in temperature

3610 = 77.3 x specific heat x 52.1

specific heat = .897 J /g°C

Unknown metal is Aluminium .
