Calculate the energy needed to raise the temperature of 10.0 g of iron from 25°C to 500°C if specific heat capacity of iron is

Question

(a) Calculate the energy needed to raise the temperature of 10.0 g of iron from 25°C to 500°C if specific heat capacity of iron is o.45 J (°c)^-1 g-1.

(b) What mass of gold (of specific heat capacity 0.13 J (°C)^-1 g^-1 can be heated through the same temperature difference when supplied with the same amount of energy as in (a)?

Answer 1

2137.5 = m x 0.13 x 475

m = 34.61 g
