A concrete block has a mass of 4 kg and a specific heat capacity of 800 J/kg∘C800\text{ J/kg}^{\circ}\text{C}800 J/kg∘C.
Calculate the energy needed to raise its temperature by 5∘C5^{\circ}\text{C}5∘C.
Use the equation:
Change in thermal energy=Mass×Specific Heat Capacity×Change in Temperature \text{Change in thermal energy} = \text{Mass} \times \text{Specific Heat Capacity} \times \text{Change in Temperature} Change in thermal energy=Mass×Specific Heat Capacity×Change in Temperature1600 J1600\text{ J}1600 J
