How much energy is required to raise the temperature of 3 kg of iron from 20C to 25C Use the table below and this equation Q mcT. Substance Specific Heat Capacity Liquid water 4.186 Ice 2.11 Air 1.00?

The specific heat capacity of iron is about 0.45 J/g°C. To raise the temperature of 3 kg of iron by 5°C, you would use the equation Q = mcΔT, where m is the mass (3 kg), c is the specific heat capacity (0.45 J/g°C), and ΔT is the change in temperature (5°C). Therefore, the energy required would be around 6,750 Joules.
