Energy Conversion Simulation
Example 6.10: Energy Unit Conversions
This interactive simulation demonstrates energy conversions between different units as shown in the textbook example.
(a) DNA Bond Energy Conversion
Energy (eV) = Energy (J) ÷ 1.6 × 10⁻¹⁹ J/eV
0.06 eV (≈ 60 meV)
The energy required to break one bond in DNA is about 10⁻²⁰ J, which converts to approximately 0.06 eV or 60 millielectronvolts.
(b) Air Molecule Kinetic Energy
Energy (eV) = Energy (J) ÷ 1.6 × 10⁻¹⁹ J/eV
0.0062 eV (≈ 6.2 meV)
The kinetic energy of an air molecule is about 10⁻²¹ J, which converts to approximately 0.0062 eV or 6.2 millielectronvolts.
(c) Human Daily Energy Intake
Energy (kcal) = Energy (J) ÷ 4.2 × 10³ J/kcal
2400 kcal
The average human consumes about 10⁷ J of energy per day, which converts to approximately 2400 kilocalories (kcal).
