Work Done In Thermodynamics

Step 1: Mass defect.
The binding energy of a nucleus can be found using the mass defect. The mass defect is the difference between the sum of the masses of individual nucleons (protons and neutrons) and the actual mass of the nucleus. For the nucleus, it consists of 2 protons and 2 neutrons. The total mass of individual nucleons is: Substituting the given values: Now, the actual mass of the nucleus is given as . The mass defect is:
Step 2: Convert mass defect to energy.
To convert the mass defect into binding energy, use Einstein’s equation . The energy corresponding to 1 atomic mass unit (1 ) is approximately 931.5 MeV. Thus, the binding energy is:
Final Answer: .
