  1. Energy Comparison Melanie Richardson

  2. Comparisons Energy to change my mass to energy. Energy for the Human Torch to melt a metal box. E = mc^2 Mass = 55kg c = 3 x 10^8 E = 55kg x (3 x 10^8)^2 E = 4.95 x 10^18 Heat energy needed to bring the box to melting point: Q = c*m*ΔT = 0.54kJ/kg K * 6795 kg * (1933.15K – 688.7K) = 4,566,260.4 kJ Estimate 50% of the box is melted Heat required to melt 50% of the box: Q = m * L = (6795kg / 2) * 419kJ/kg = 1,423,552.5 kJ Total energy expended: 4,566,260.4 kJ + 1,423,552.5 kJ = 5,989,812.9 kJ

  3. Conclusion • The energy required to change my mass to energy is 4.95 x 10^18 • The energy the Human Torch expended was approximately 6.0 x 10^6 • The energy that is required to change my mass is 8.25 x 10^11 times more than it took the Human Torch to melt the titanium box.
