Answer to Question #158908 in Physics for Annie

Question

The specific heat capacity of iron is 500 J kg^-1 K^-1. The quantity of heat required to raise the temperature of 500 g of iron by 2 ºC is:

Answer 1

$$Q=mc\Delta T,$$ $$Q=0.5\ kg\cdot500\ J\cdot kg^{-1}\cdot \!^{\circ}C^{-1}\cdot2\ \!^{\circ}C=500\ J.$$
