SUMMARY
To calculate the joules required to heat 40 kg of water by 20°C, use the formula Q = mcΔT, where Q is the heat energy in joules, m is the mass in kilograms, c is the specific heat capacity of water (4,186 J/kg°C), and ΔT is the temperature change in degrees Celsius. For this scenario, Q = 40 kg * 4,186 J/kg°C * 20°C, resulting in a total of 3,348,800 joules. This calculation is essential for understanding thermal energy transfer in physics.
